Jegus, it's kind of startling to think that only twenty years ago "gay" was simultaneously a go-to playground insult and still enough of a Black Spot to get you professionally pilloried.

And Seinfeld wonders why it doesn't work as a punchline anymore. :x

You can find remenants of the old fandom in some places, probably maybe a discord group. It's rare, but the combat enthusist bros..especially on roleplaying. Those guys take their Ph.Ds in "whoopassery" very seriously. Every debate probably always has lengthy discussions and sometimes even arguments, if you like that flavor of tea.  You might still run into homophobia though sigh. It's thankfully less common now but I still see blatant anti-LGBT rhetoric in some fandoms. I don't think Naruto has too much of it, but certain game fandoms like Souls-like, anyting medievalish, and -surprisingly- niche japanese indie games, even ones where 99% of the characters are females attract some um..interesting people. 

@lua0: Okay yeah I also remember people who liked to godmode or fight over powers and stuff, and witnessed the creation of many side group chats made for the sole purpose of excluding someone in the main one from it.
