Some of the most closed off boarder and hard to get into countries are left wing (peep those immigration standards for European left wing countries). Right wing capitalist countries are fine with it because they need cheap labor for their capitalist machine. Not to mention, those people end up here because of us in the first place.
What are you even talking about? Literally no one is in favor of closed boarders. The only reason you'd think left wingers are is that you're a drooling idiot who consumes too much right wing media.
The thread tells me quite a bit about what time you're on
