Like, I know at best they're ambivalent about things like racial and gender equality. But do you think they ever wonder why their movement is almost exclusively white and male? Ever cause them just a bit of self-doubt? I mean, one reason I know socialism/leftism is right and good is the fact that what we stand for attracts people of all backgrounds (at least IRL, not sure about online).
Former libertarian speaking:
No, for two reasons.
If you're a libertarian who actually hangs out in a physical space with other libertarians then its an almost statistical certainty you're a rich white kid who hangs out with other rich white kids.
If you're a terminally online libertarian gamer type who is socially awkward and never logs off (like I was) then you get insulated from that moment of realization because everyone you know is behind a computer screen.
