My family has also bought plots in pindi-islamabad, the ones who sold it to us, were your potoharis/punjabis. So you should be frustrated at your own people.
Pashtuns have migrated eastward since long, either due to wars in their watan or for oppurtunities. In those times, vast stretches of hindostan upto bengal were opened to them. Nowadays they cant go beyond wagha. So it would be either punjab or sindh, but only in their urban centres.
About your day dreaming of committing genocide of Afghans in Potohar, thats not gonna happen for various reasons. If it was that easy, indian mohajirs would have already committed genocide of pashtuns in karachi or sindhis would have already cleansed sindh from all kind of settlers. Your scenario can only happen, if attempt of genocide is backed by state, carried out by army (punjabi and pathan civilians themeselves are o.k with each other, so rule out your 47 dream)....as happened in 1971 with bengalis, when jawans from potohar could not control the lust and thirst for women and blood.
For qabail or any pashtuns, the threat is not from some lalu panju civilian from potohar or else where, Its highly trained professional army with guns, tanks, artillary, jets, gunship helis etc. Khaki jawans are losing 'temper' with each passing year, raheel shareef has shown that he is ready to move the level of 'punishment' to next level. Honestly speaking british never faced such dangerous enemy like TTP from pashtun belt still they faced a low intensity insurgency for 100 years led by mullahs, malaks and faqeers. TTP's ambushes on security forces would go on for several decades. Lets see when first rape of pashtun woman occurs by faujis and let see what would be the response of general pashtun population, as well as those in FC and lower ranks of the army, to the incident.
How did you buy property? I thought Afghans weren't allowed to buy property in Pakistan. You aren't a fake cnic holder are you? And we are not hindustani Karachiites either.. We also have a history. We've defended our lands on our own without any state intervention. And Pakistani pakhtuns can only stay as a minority. If they threaten our existence, there would be no distinction. Afghans have no belonging to this land, and their mere presence is a blasphemy here. My hate is reciprocal. I wasn't born or raised hateful, but grew to hate them over the years. If Pakistan implodes, god forbid, we'll see who stays and who leaves. And yeah, you're right. A genocide can only happen in case of chaos like 47.
Also Afghans have always backstabbed all the muslim speakers of indic languages. There was a movement in late 1800s, where muslims of India decided to migrate to Afghanistan in masses, but were denied entry into Afghanistan.
As for the hindustani karachiites, had they not been pacified by the army in 90s, things would have gone much messier. Truth is, Karachi based Pakhtun gangs are no match for MQM's militant wing. MQM's militant wing is notorious for its intelligence gathering unit. There were reports of Pakhtun reverse migrations from Karachi in 2010-2013 due to Zulfiqar Mirza affairs. Economic Pakhtun migration has more or less stopped going to Karachi. Some Pakhtun families are even shifting to Islamabad from Karachi.
And Potohari soldiers raping Bengali women is a lie constantly repeated by Afghans on Pashtunforums. There's no evidence of Potohari soldiers indulging in rape. Martial race theory was abandoned back then even, and hence a non-martial Zia and Musharraf were in army even back then.
You punjabis have habit of generalizing and stereotyping about pashtuns, whether positively or negatively. Pashtunwali is like belief and religion, some follow it, some doest. Some live upto it, some doesnt. I.e a pashtun can be imaandar or bey-imaan, a ghairatmand or beghairat, brave or coward. But like most of the societies, we look down upon vices and sins and cant accept it as norms. E.g you yourself said that many afghans in your area are earning through hard work e.g tandoor and labour. Yet you chose to make your opinion about them from some extortion cases in which afghans may or may not be involved.
Qabaylis and Afghans are involved almost exclusively in carjacking and kidnapping for ransom. There was a 275% increase in kidnappings from 2012-2013(can't cite the source now). If I was a racist, I'd dislike all non-locals, and even plain punjabis, yet I don't. When a guest damages the host's house, you force that guest out or at least lock your door. And there have been hundreds of Afghan arrests in recent years. Whenever you read the Islamabad section on news, it's always "Afghan" or "xyz were speaking in Pashto" news. Secondly, majority of Afghans carry special hate and derogatory terms for us like "daalkhour", yet stay and leach off the economic benefits of our own hardwork.
And secondly, Pakhtuns themselves, including Pakistani ones, are quite racist in general themselves. Ask any non-Pashtun who has lived with them.
There is no honour in that, not a single sikh was harmed in pashtun belt due to code of pashtunwali, even though muslim leaguis were instigating them to do so. The sikhs in peshawer and FATA, came with ranjeet singh forces yet it didnt provoke us to massacre them, even though hari singh nalwa spilled lot of pashtun blood. Instead of killing sikhs under our protection like cowards, our battle hardened tribesmen were eager to go to east punjab and kashmir to avenge deaths of muslims as evident from telegram of liaqat ali khan to nehru (but were directed to kashmir only by pakistan).
What people of multan did, was honourable and islamic.
The Sikhs in Fata and Peshawar were local merchants and not really jagirdaars. The Sikhs in Potohar were settled as jagirdars. Sikhs didn't try to commit genocide of individual Pakhtun tribes like they did in Rawalpindi and Murree hills. And back then, Seraikis and Potoharis had no distinct identity but were all "Punjabi". The head of unionists was from Attock but always said "I'm a Punjabi first, and muslim, Hindhu or Sikh later". Sikhs had attacked Punjabi muslims in east Punjab. They had to be returned the favour.
And hundreds of Azad Kashmiri volunteers also took a part in qabayli incursion. The "faateh-e-bhimber" was an ex Indian army member from Bhimber, who formed anti dogra militia from retired and serving soldiers of Indian army. The whole anti-maharajah movement was started by Gilgit Baltistanis any way.
There are also hindu rohilla rajputs in Rohilkhund , even though rohilla is synonymous with pashtun. When i dig deeper, i found out that rajputs of kumoun and rohilkhund, who were under rule of rohillas, served under various chieftains of rohillas. Kumaouni, garhwali and katehr rajputs were martial hindu people so they were recruited by rohillas. They got labelled as rohillas and use surname of rohilla. Same must be the case with sudhans, who were declared "martial race" by british, were heavily recruited and it was not no coincidence that they rebelled in poonch. They have khan surnames. And they are very clear and loud about their sadozai origin, which shouldnt be so surprising for you as sadozais have ruled kashmir for 67 years. Sudhans are too much martial to be brahmins.
Brahmins are known to be good fighters. The generals of Hindhu Shahi army were Mohyal brahmins. East India company had used bengali brahmins as their cavalry.
