I think the primary argument and one i don't REALLY disagree with, is that currently quantity is so fucking high it doesn't really matter the WHO.

The flow has to STOP first before we can start qualifying. So making the "we'll a few thousand Germans made operation paperclip a success" is irrelevent from both directions.

I'm objectively racist. Like "some races are born inferior to others" racist. I'd STILL say that on balance a few thousand shitskins is PROBABLY easier to deal with than several million "good ones"
