There is nothing that great about that kind of diversity.
If we have a diversity of skilled workers coming over legally, that would be fine.
The diversity here means just different, lacking skills, language or anything we can make use of.
So ride them out of town every way you can.
And the idea that there's no 'right or wrong', that everyone is right, that no culture is better than any other culture sure doesn't help.
People (Liberal university professors) with these notions should go to Cuba or some other sh1thole third world country and say 'this system is just as good, better even, than the evil American dictatorial system'.
And hopefully stay there, never to return - good riddance and goodbye, I'd say.
