While an interesting read, although too long for no points delivered.
I fail to see how the only point summarized — “racism” is even there. Racism according to many definitions must include discrimination. Some even go as far as to say it should include a power to enforce discrimination (I personally think this is bogus one, power is fluid). Wanting to keep your culture in your home or around you, without discriminating doesn’t really qualify as racism.
It is certainly an interesting study in double standards. But you are going way too far in allegations.
