America and other puritanical places need to get over their aversion to nudity, this is true. But that's not going to happen by yelling at people over something that is a very new topic for many (yes, trans people have existed forever, but their widespread visibility is extremely recent). The culture war is absolutely being lost, and it sucks because it's over a very vocal minority since most trans people are fully aware that there needs to be an adjustment period for things like this and we aren't there yet.
Side note, I have a rape victim acquaintance that for years couldn't even be in the same room as a man, let alone be anywhere near a penis. She very likely would have had a genuine ptsd breakdown if she was at that spa and saw a penis, regardless of if was attached to a man or a woman. I wonder what Era would say to her. Maybe something along the lines of "why are you going to a nude spa if you're traumatized by genitalia" or something.
