Someone asked what rape culture is.
Rape is sex without consent. It is not just sex where a woman is struggling and screaming no.
Rape culture is (amongst other things) a belief that having sex with a woman who is too drunk/high to give consent, or who is even passed out, is not rape. Or is "not so bad", "not a huge deal". Take the Stuebenville trial for example. I don't believe those kids are monsters, I just believe they are extremely dumb and they grew up in a culture that eventually led them to hold the abovementioned beliefs. They are still rapists. But look how many people defended them and their actions. Look how much media attention was devoted to 'what a shame these young mens' lives have been destroyed' instead of the impact on the girl.
Rape culture is also the belief that if a woman is initially reluctant, it's OK to keep pressuring her until she gives in. So long as she's not saying no while your dick is in her, it's not rape. Great example is this scene from Rocky:
Rape culture is when people shift part of the blame for rape onto the victim. "What was she wearing?", "was she drunk?", "was she acting slutty?" etc.
