Not very sure about that.I have seen many people in mainstream Pakistani Media Bashing Sikhs for their role in Violence during Partition.I have seen Hassan Nisar , Zaid hamid etc Talking about how Sikhs used to kill innocent Muslims Migrating to Pakistan.Also on Some other threads I SAW a Lahori guy saying that the kids there are taught to hate Sikhs.Also in some areas of Pakistan "Sikh" is Considered as a "Gaali" ,in a Youtube video Tarak Fateh Pakistani Canadian was saying that He was told in Childhood that Sikhs and Hindus are dirty People.While talking about Partition violence they do not mention the violence committed by Punjabi Muslims upon Sikhs/Hindus, in their books kids are taught that Sikhs and Hindus massacred the Muslims and the Muslims were doomed in the indian Punjab and Hindus and Sikhs were given safe passage by Muslims of Newly created Pakistani state.
Some excerpts from Pakistani School Books
* "After the establishment of Pakistan the Hindus and Sikhs created a day of doom for the Muslims in East Punjab" Class X
“The Muslims of Pakistan provided all the facilities to the Hindus and Sikhs who
left for India. But the Hindus and Sikhs looted the Muslims in India with both
hands and they attacked their caravans, buses and railway trains. Therefore
about 1 million Muslims were martyred on their way to Pakistan.”
“Sikhs destroyed the Muslim towns from the river Sutlej to the river Jamna. A
number of times the Sikhs crossed the river Jamna and looted and destroyed the
settlements of the Muslims. They turned the mosques into their ‘Gurdawaras’,
demolished the shrines of the Muslim saints and burnt religious schools and
libraries.”
There are probably more , So I really have doubts that Pakistanis have forgiven and forgotten.And recently there was a book by a Pakistani which Talks about the Sikh Plan to Wipe out Muslims from eastern punjab.

And The two nation theory is not only relevant with Hindu and Muslims it is also relevant among Muslims and Sikhs, our heroes are there villains and vice versa.Sikhs consider Abdali, Aurangzeb etc as Villains and tyrants whereas in my knowledge Pakistanis Punjabi consider them as heroes ,fair and just rulers who did great things for Islam and i haven't seen one Pakistani criticizing them for the massacres of Sikhs and Sikh gurus however i have seen plenty of them taking pride in it... They are Heroes for them.Whereas Sikh Heroes like Maharaja Ranjit Singh ,Hari Singh nalwa are considered as cruel and tyrants by punjabi muslims who think that they used to persecute Muslims and used to destroy and turn their mosques into stables ,used to forcibly convert them and massacre them.he is probably considered as villain as far as i know.The Sikh reign (confederacy and Empire) is also considered as the Dark(est) period in the history of region,whereas Islamic rule is considered as peaceful (Sikhs will Disagree with that).
The era of internet also will not help in people forgetting the differences.People will never forget when they see the one sided stories of Survivors and refugees and how Sikhs Killed Muslims and forcibly converted them.And pakistanis Punjabis Consider that it was the Sikhs Who were responsible for STARTING the Violence and they hardly and reluctantly admit the violence committed by their People,videos of movies like GADAR and Partition etc also rekindle the hatred.
Its not about culture and Language these things take a back seat when it comes to politics or religious politics.Even if you leave out politics A Punjabi Muslim would Support a Muslim of any ethnicity/race/culture over a Punjabi Sikh and vice versa on a conflict (all things being equal)2002 Muslim (Gujarati) massacres will probably bother them more than Sikh Massacres, I have even seen many of them saying that it 1984 was a punishment to them by Allah for what they did to Muslims in 1947. A PUNJABI Sikh is not a part of Ummah.Sikh muslim can get along very well if they are only looking towards common things like Bhangra,Food (they might quarrel over jhatka and halal though), ,Music , Language (Gurumukhi Shahmukhi conflict may arise) etc but these are not just the things which will appear and will be there to deal with when you live with each other for a long period of time with Sizable population and if you want to dilute Borders.You can only live together when you are forced to live together by a third party (like Imperial British,Or a Secular govt etc), or when one community forms a negligible minority not strong enough politically or Militarily to oppose dominance of one culture (which is the case in Both Punjabs today when SiKHS and muslims do not have much problem) , but when there is a sizable population of both communities on both Sides and if both are politically and militarily strong enough and there is no umbrella of a Superior third power to Check them , the conflicts are bound to arise over differences of Religion, ideology,script etc.Sikhs being welcomed during their Pilgrimage and muslim Punjabi artists being loved by Sikhs is not related to politics or Demographic changes, conflicts arise when one side feel insecure about the dominance of other and is strong enough to resist, which will be the case if borders are removed. So Border is there for a very good reason.
These are my views no offense to anyone.
