I don't think it'll get you looked at funny in public, most places, at least, I really hope so, for half my closet's sake, right. But it's definitely become associated with the proud boys and "boogaloo boys". The boogaloo being a word used to describe a highly racialized civil war, purge, day of the rope, what have you, which is coming any day now, rapture style. I think mostly derived from stuff like the turner diaries. A lot of them end up wearing hawaiian shirts because it goes along with their post-ironic fashwave aesthetic. So, probably don't wear a hawaiian shirt to your protest, but, you should've probably been going in black bloc stuff anyways.
God damn, I have terminal online brainrot, huh?
