Ken the Hen is exactly right: LEAVE THEM ALONE.
I remember genital inspections — only we called that junior high PE class. I hated it. Being an insecure and introverted adolescent and being told to strip and take a public shower was bad enough, but it was made worse by the swaggering asshole, Mr Earl, who ‘taught’ PE and would stroll through the locker room making comments about everyone’s bodies. He was definitely in the category of “really mean people”, and was probably also a white supremacist — he certainly raved on and on about the Vietnam War — and I’m sure he’d be a TERF, since, although there were very few openly trans folk in my community then, he was dazzlingly homophobic.
OK, maybe that’s my conspiracy theory. The worst people in the world are brutal PE coaches from the 1970s, and now they’re all running the country and sitting in the Missouri legislature passing hate crimes as laws.
