Sorry to but in, but I think I can contribute tbh
I'm in Saudi (not UAE, but similar) right now, and I can assure you, the Arabs here treat Pakistanis like ****, they make jokes about us, there is institutional racism in their legal system, they give us all the **** jobs, **** Arabs. It's got to the extent that I know Pakistanis here who won't speak Urdu in public. Feel like having a massive rant about Arabs, but will keep that for another time...
I've also commented on that thread, and that guy, is broadly speaking, correct. Pakistan is slowly becoming more Islamic. Over the last 30 years this is the case, and that is indicative of a broadening divide with India. Pakistani Punjab is still fairly comparable with Indian Punjab. Fairly being the key word, the language is the same and the culture is fairly similar. But the religion is different, and that still makes for big differences. I guess you could compare the richer parts of Karachi, Lahore and Islamabad to Mumbai, Delhi, but you can compare rich people in every part of the world tbh. Views like that are very common in Pakistan, but I think people are a bit more open over here. I don't have any deep hatred towards Indians, and I've got lots of Indian friends. It's because they're all Punjabi, so we have a comparable culture. When I have met Indians from the South, they're very different, they do have considerable cultural differences, and in a few cases, they aren't very friendly. In the UK, asians generally get along, yep.
