Doubles are a weird subject for me.

To put it shortly, I don't dislike doubles, as long as that particular double is also okay with being doubles. If someone says they don't like doubles for kin A but they're okay with doubles for kin B, I'm fine with seeing stuff about kin B regardless of the content. But I won't be fine with seeing them talk about kin A, because they don't like doubles so I won't like this double either.

But please don't post stuff like "I am the ONLY one of this kin that is valid!!! ALL DOUBLES ARE FAKE!!!"

Even if it's a character I've never even heard of it's gonna make me feel gross. So if you can't refrain from venting in that way then at least put it on your story or something so that you can hide me from it.
