It seems like a lot of reviewers think that because you're exercising your freedom of speech, no one can be offended. I'm not sure I understand that "logic"...
Some of the artwork was pretty good (i.e. the first movie), but the quality wasn't consistent. It's hard to tell if this was all made ironically or even doubly-ironically, so I can't really comment on your intentions to offend...perhaps you're mocking people who make offensive things just to provoke people? Can't really say.
However, because it's not obvious, you're giving way too many obtuse gay-hating metal-listening highschoolers boners, so next time just make something that's inherently creative and interesting, okay?
