They fucking are, though.
I was at a Bad Religion gig once, and one of these just would not leave me the fuck alone cross-questioning me about my (non) gender presentation and just followed me around debating my existence.
I'll add that the week before, I'd been at the same venue, at a folk metal gig (Turisas), a few people asked about my gender (which was the same non-gendered presentation, only with warpaint and actual armour, because I've never met a bit I won't over-commit to) and there were all 100% respectful.
