I'm ... confused. First of all, like Blenderudit said so fittingly, every bigger community / fandom has a bit of drama and some people who are not nice to be around. I think it's not about whether a fandom has these, but how many there are and how the rest of the fandoms reacts to them - if there's a tendency to just let these angry people be angry and rude and spoil the fun for everyone, it certainly spoils the fandom for me.
To be honest, I don't know what you're getting at here. You are in a Kingdom Hearts forum where you just plainly said you distance yourself from this community. Which is fine if you feel like that and it would also be fine if you had actual arguments or suggestions about what we, in which I mean the forum KH Insider, could do better. I've read from a lot of gay / bisexual / pansexual / diverse here, so claiming it's all homophobic here is something I simply don't see. And I've never read anything about furries, negative or otherwise, just absolutely nothing. So it's really weird for you to come out and lash out at this forum's community to be anti-furry in general when most of the people here have never said anything about it (for example, I personally simply don't care about furries, whatever makes people happy and does no harm is fine). Not trying to insult you, but your statements come off very rude. It's great that you embrace yourself, it's great that you feel inspired by people (e.g. Ariana Grande), it's great that you feel comfortable with who you are, but that doesn't justify labeling everyone as being mean, homophobic or anti-furry - that's like saying "I'm gay and if you don't love my posts, you're homophobic". Also, as a gay myself, the way you talk about closet furries rubs me the wrong way - sometimes people have good reasons to stay in the closet. Maybe they can't come out, maybe they don't want to come out just yet, maybe they're dealing with other shit, also you don't always have to come out if you don't want to in the first place. Your post feels a bit like "everyone should just come out and everyone else should just be happy about that", yeah, I also wish that was the case but it doesn't always work that way, so one can legimately get angry at people who are being shitty about it, but we can't just dictate people how to come out or to feel (homophobia excluded, that's just not valid because it oppresses others).
Well, I dislike Kairi and that certainly didn't show me anything, but your post showed me. I feel like the way your post is worded, you're very actually very iffy about other people's opinions when they differ from yours. I really, really don't understand what's to like about Kairi, I find her highly unlikeable, but well, can't go around and say "listen to me, Kairi is shitty, why don't you just get that?!". Opinions don't work that way. It doesn't work in ways of "hah, I showed you!", either you can convince people or you can't. When you don't like the general tendency of a fandom, e.g. if there are more Kairi haters than lovers, you can leave or look elsewhere (e.g. in another forum), but don't make people sound dumb if they don't get or share your feelings on something.
Oh and topic: I distance myself from the Dragonball: Dokkan Battle community. Terrible community, there are way to many people who believe liking a female character makes you a "simp" while liking male characters is often commented with weird sexual slang like "[new male unit] turns me so on", it's just childish and inappropriate and weird. Oh and there's a ton of people who think anything less than a hardcore player is a noob which is equally annoying. Ugh.
