I don't disagree.
That said, I'm going to say a thing. I offer it not as an excuse, but perhaps as a part of an explanation. Milo was, in one respect, correct: A lot of gay men know what he meant, because it happened to a lot of us. There was - and to some extent still is - a culture of the older partner showing the younger partner "the ropes", as it were. I, too, had my first relationship with someone considerably older than myself. I was 19, it was legal by any standard, but yes, it was still sketch. I stop short of saying the relationship was abusive per se, but it wasn't healthy.
I don't think it's a healthy thing, I don't endorse it, I merely say it's a thing that exists.
I think part of why it exists is because for a long time, a person coming to terms with being gay didn't really have any idea what to do with that knowledge. Hell, I only came out a bit less than 20 years ago, and even back then, it was... Gay people were a thing everyone knew about, but they were still largely relegated to comedic roles in movies and shit, and the first attempts to talk about being gay in school sex ed classes was still controversial and not wide-spread. I mean, beyond a general understanding of some of the mechanics, I didn't really know what it meant to be gay when I started to realize I probably was gay. Which creates an environment ripe for shit like that.
Which, again, I stress, doesn't make it a good thing. Because a lot of old fags, particularly those who have an interest in the young and vulnerable, have some pretty fucked up ideas about what it means to be gay. It took me a few years to work through and overcome a lot of the toxic shit I was taught.
...
Dunno what my point is, exactly. I'm rambling.
