YOU wouldn't know logic if it picked you up and dropped you on your head. You produced ZERO evidence to support your faulty claims.
My logic is sound.
Efforts at assimilation are fought against by society.
Diversity is celebrated at almost every turn (the exception being any white or conservative culture).
Unlimited and unending immigration leads to every growing sub cultures instead of shrinking and assimilation.
Every higher percentages of foreign born leads to minorities becoming local majorities that have nothing local to be assimilated INTO, and instead become dominate local, and less local every day cultures.
