I think this is more of the "with us or against us" mentality. I'm definitely not on right yet I'm sticking up for them a lot lately because because all "the left" is doing is yelling at people about racism and misogyny, not to mention a lot of other crazy stuff like cultural appropriation.

Not to mention, a lot of the "alt right" is not particularly right wing at all, some (like protectionism) is even left wing.
