I see a lot of posts hating Indians on 4chan so wanted to know if that's the case irl in western countries.
It depends. Some people don't really like others emigrating because their own countries are bad. It doesn't really improve the West to accept non-Westerners. It doesn't help that Indians bring the caste system with them. I personally find it funny that there can be two Indians practically identical, but one thinks he's so much better than the untouchable, and meanwhile I'm just a white guy looking at two Indians.
