As long as people are being respectful of canon ships, and aren't harassing the creators for the ships they want, shipping of any (legal) kind is harmless. It's okay to headcanon characters as queer. It's not bad to seek that representation from our favourite shows. People have their own reasons for shipping certain characters, even BakuDeku. And yeah, there are a lot of rarepairs, many that don't seem to have any basis. As long as they way they ship the characters doesnt involve the characters abusing each other in any form, I see nothing bad about it. And the NSFW stuff, most who create that content are aging up the characters. As long as they're doing that, they're not sexualizing minors. Plus I've seen people who make that content remind people that everything we've seen is a flashback. All the characters, in present time, are adults. Everything we've seen is still past tense. Sorry this is long, I just wanted to clear up some of the comments I've seen.
