> You can't judge people with "what if they did X".

What I'm saying is that at some point, someone's behavior will become toxic to "your group" (not the whole US - here, the "tech community" however you want to define that) and then they get asked to leave.

This is actually the mature thing to do, to part ways, as opposed to escalating conflict where the same thing happens in the end but the participants are left bloodied and hurting after the in-fighting.
