This is one of dumbest logical fallacies I've come across. There's no way "Bollywood is ruled by Muslim actors" but even if we accept that for that sake of debate, just because people from a certain background or community have been able to become successful doesn't mean there isn't systemic discrimination against people from that background, there are numerous successful African-Americans that doesn't negate the discrimination and institutional racism most face. There are a few successful Asians in the Hollywood yet many are still aware of racist stereotyping and typecasting that still goes on Hollywood. Just like how you say Pakistan doesn't represent Islam, likewise a few Indian actors who happen to be Muslim doesn't represent Islam or the Muslim community at large, besides most of them are non-practicing/secular/nominal Muslims by their own admission, so the rest of the Muslim world and Indian Muslim community they aren't really considered representatives, it's like calling Freddie Mercury a good representative of the "British-Indian diaspora" when he never really identified with it/has any connections with the community.
