African diaspora nationalist movements like Rastafari and the Back-To-Africa movement believe that Africans don't want to live in Africa because they're brainwashed by Whites and/or Jews into not wanting to go to Africa. The truth is, by their own accord, they would never want to leave America or Jamaica or whatever to go back to Africa, because then you would have to deal with Africans. The same is for India. Ever since their country technically industrialized, they had no clue how to deal with their own pollution, and it's probably not going to get better. They, on their own accord, are causing ecological disaster that climate change people had worries about for decades, the difference being that we know how to deal with most of our pollution and trash, and we have functioning dumps and water treatment plants.
There will never be enough elite Whites and Jews dead for the wool to be lifted over the eyes of Indians to see how cringe they were as multicultural advocates and become nationalists residing in their shitheap because they were never multicultural advocates, they're opportunists exploiting the multiculturalism that liberal Whites and Jews hold, like with everyone coming from the Third World. It's like in Wall E where the earth is ecologically dead due to pollution, so they built their own spaceships to escape it, except it is happening only in South Asia and they don't need to build spaceships, they can just move here, or they just continue living in the trash skyscrapers being none the wiser.
tl:dr they are not going to change their mind about wanting to live here because they aren't ideologically motivated, they are going to fight tooth and nail to stay, like they always do.
