Sex and Violence in Supernatural

So in general I've found Supernatural Season 4 so consistently and absurdly sexist it's often like watching a hilariously wrong parody. This episode took this to it's logical conclusion, it's like someone wrote a deconstruction of the show and sneakily disguised it as a regular episode.

I watched the first 5 or so minutes of this episode then stopped and went to Cam.

Me: I need to know if this episode is going to piss me off as much as I think it will.
Cam: Which one is it?
Me: Well, it starts with a beautiful blonde woman who is viciously bludgeoned to death by her husband for no apparent reason. And now it looks like it's all the fault of an evil woman.
Cam: You are going to have to be way more specific.
Me: It's an evil stripper.
Cam: Let me look it up....Oh that episode. It goes somewhere interesting, trust me. You should keep watching.

And I did, and then I went "OH. I remember hearing about this one. Hee."
