So rape culture, basically, is the idea that rape has degrees. Like, if a black man rapes a white middle aged suburban housewife with 2.5 kids and a loving husband, that's a bad rape. He goes to jail. But if a white college frat boy rapes a Latina woman he met at bar, and she was wearing somewhat skimpy party clothes and had trace amounts of alcohol in her blood, well, that's a maybe rape. Like, maybe she was willing at the time but changed her mind later when she was diagnosed with Chlamydia. And joking about rape contributes to rape culture because it gives rapists the idea that women aren't really unwilling, they just like to say no for the record so they feel less ashamed about one night stands in the morning. Am I getting this right?
