Please don't be a blind person.
Just look at the crimes of Turkey. Just look at the Genocide of millions of Armenians. Just look how the whole west Armenian is today a part of Turkey and nobody even utters a word about it. (You also uttered not a single word against it and just neglected it, which is a shame).
And what about the killings by Azeri Governors of the Armenian population of Nagorno-Karabakh under the colonial rule of Iran and Russia?
Today you say that Hamas has all the right to kill Israeli civilians while Jews illegally occupied this land. But when Azeris did the same under the colonial rule of Iran/Russia, then you shut your eyes.
What are you going to do now? Again show the double standards and neglect this issue of Armenia while they are not humans in your eyes as they are Kuffar? Do you want to say that only Muslims of Hamas have all the rights but non-Muslims don't have equal rights?
What merciful?
Killing war prisoners is merciful?
Raping all women and girls by making them captives merciful?
Looting even the last penny is merciful?
Separating small children from their mothers and selling them in Islamic Bazaars of Slavery is being merciful?
These were the crimes of Muslim ancestors for the last 1400 years, till the Caliphate existed and till the non-religious West didn't kick on their back and forced them to abolish slavery.
The colonial British Empire also committed crimes, but they were nowhere close to the crimes of Muslim ancestors.
The colonial British Empire ruled almost all Muslim countries, but it abolished slavery in its colonies and didn't rape women, otherwise, your grandmother and my grandmother all would have been raped by white colonial people, and you and I were from a progeny of any white person.
Mughal rulers decided only to take Jizya and not to kill the war prisoners or enslave them all. Muslims were never in such a majority to rule over the whole of India. Muslim rulers were divided among themselves too.
Ibn Battuta: How Muslim Rulers took Hindu Princesses as slaves and raped them
Ibn Battuta writes about Sultan Muhammad Tughlaq:
Has Israel committed such heinous crimes against Palestinians? No.
Has colonial powers of the British Empire or France committed such crimes as colonial Muslim ancestors did? No.
Did the colonial Britishers and the French did such a Genocide as Turkey did of Christian Armenians? No.
But the problem is your double standards.
Yes, they did it and for that we condemn them and as consider them war criminals.
But do you also then condemn the war crimes of your Muslim ancestors and condemn them?
If not, then why these Double Standards?
Grapes are sour.
You don't have the power to invade non-Muslim lands, otherwise, you are no angels.
Your hero Saddam Hussain was one of the cruellest people who killed millions of Shia minority people and killed several hundred thousand Kurds.
Do you remember how Saddam Hussain killed 5,000 Kurds in one night when he bombed them with Chemical Weapons in Halabcha?
Your Muslim Heros of today didn't get power over non-Muslims, then they started killing their own Muslim brothers.
And your Muslim Caliphate of Turkey killed millions of Armenians in not distant past, but again all such killings for you are Halal Allah and the blood of non-Muslims have no worth for you.
