His conquests enabled Islam to flourish across Afghanistan and Pakistan, and he greatly influenced the culture of Pakistan.
He torched and depopulated the old city, but then rebuilt it into what is now Lahore, and other people from his empire then moved in to repopulate it. And this doesn't change the fact that Lahore was his winter capital.
They probably aren't my ancestors since they all either got killed, ran to India, or were enslaved. And I already told you, many people from Pakistan (and even India) fought in his army:

Exactly, Pashtuns and Indo-Aryans fought in his army. Both groups are present in Pakistan, so for you to say "lol he crushed your ancestors" doesn't make any sense. Especially when most Muslims from Pakistan and northern India are (partially) descended from people who came to the sub-continent during these conquests.
Doesn't change the fact that you lost all the other wars with Pakistan (other than the one that took place in the Siachen), or that Muslims completely battered your country for hundreds of years.
And trust me when I say most Pakistanis have never cared much for Bangladesh, even back then. They just generated revenue for the Western mainland via their agriculture, only a select few of them were ever actually valued as equal citizens (not saying I approve, but that's the blunt truth).
I must say I'm disappointed that you, as a think tank, resorted to saying petty (and incorrect) insults constantly repeated by Indian trolls such as "lol your ancestors got rekt" and "we broke you in two". We were having a perfectly normal conversation. But if you want to be like this, I can play along.
I also don't understand why Indians are so obsessed about ancestry. We are Muslims, so naturally our heroes would be (no surprise here) other Muslims. What's next? Are you going to say we can't be proud of our Prophets (peace be upon them all), or their companions (may Allah be pleased with them)? Countries, like we have today, weren't even a thing back then. In those times, there was only Darul Islam (Muslim land), Darul Harb (hostile land), and Darul Ahd (land which Muslims have a truce with). That's how we (practising Muslims) view history.
Wrong, he had Indo-Aryan generals such as Tilak.
