actually a lot of horror movies are more progressive than regular old mainstream stuff. there's movies with mixed race couples that aren't the entire plot, movies where women get revenge on rapists, movies presenting white men as ultimate monsters, there's even movies showing women as the hero that saves the day. they're all indie horror with lots of gore, usually, but there's a codified set of rules about horror plot structure that allows them to cast actors of every color and gender with no concern at all. it's integration at its finest, even in some of the schlockiest movies.
I mean even pighunt has a woman pee o cee as the hero character, there's a mixed race couple and nobody even mentions it.
then again there's a lot of tits and ass and gore.
now, if they get started on Russ Meyer it'll be a shitshow.
