The multiverse thing always gets me. Do they really believe that alternate universes are just animu fantasy lands where Sonic is totally real and totally from your canon? And don't forget past lives. Because you can totally be the reincarnation of a character that was created two years ago even if you are a 35 year old furry living in mom's basement. And somehow it all totally makes sense because quantum physics or something.
Favorite characters never get together and have 16 hours of hardcore buttsex every day? That's ok! They do in your canon! And you happen to be kin with both of them! Lube up!
Hot bishounen genetic abomination with long silver hair a little
too murderous for you? That's ok! Because in your canon he's just misunderstood and lonely. If only people knew the real Sephiroth. Then they'd understand.
It's all just a very bizarre and unhealthy variation of fanfiction. It's not enough to write about alternate universe scenarios. You need to tell people those scenarios are totally real and you totally are that character. If they disagree with you then they are being kinphobic and should kill themselves. But please totally tag all suicide mentions as a trigger warning.
I think this might be the worst one I've seen yet because it's encouraging possibly unstable people to embrace their delusions.
