As a queer guy wearing nail polish, I have a different (though not negative) experience. In my experience people do notice it, but often either give compliments or make slightly bigoted remarks that can be pretty easily laughed away or countered. I haven't come across anyone who was a total asshole about it up until now though, even when I pivoted to colours that weren't black.

It's also not that I'm a necessarily queer-positive environment or that people support it because of my queerness. Both family (apart from parents and siblings ) and colleagues are generally not aware that I'm LGBT+, and they're also usually leaning slightly "anti-woke". But at the same time they also seem to abide by the Dutch "live and let live" mentality. It seems like they just think "oh cool, he's a guy who painted his nails", which is definitely better than I was expecting of some of them.
