If they're the stupid jerks you've portrayed, they probably would do that without even watching it first, nor hearing what hyper-badass Satsuki's views on nudity.

If you go into something expecting to hate it for ideological reasons, you're very likely to come out of it hating it for ideological reasons. It's easy to rag on people for declaring that they hate something without exposing themselves to it properly, but in fact the level of exposure matters much less than you'd probably think.

I haven't watched much of Kill la Kill (for lack of time, not lack of enjoyment), but I've run into this problem in conversations about quite a few bits of media that I think of as bona fide classics. I've almost certainly been guilty of it myself too, of course.
