Now, I'm not gonna give into purity politics and say that people who like ships that I don't like are abusers and should be burnt at the stake.
It does say a lot about the KLK fandom, though, that they're more eager to ship Ryuko with an abusive, manipulative sociopath or her literal sister than to put her with Mako, who canonically starts dating her.
Like, these people literally headcanoned that Mako is dead and has been replaced body-snatchers style by the aforementioned absuive sociopath. That's how much they want to avoid shipping a healthy lesbian relationship.
