It's definitely not rape. But abusing someone just because you can get away with it is still extremely antisocial behavior and she has every right to use her free speech to make sure everyone knows he's a sociopath.
Also, in your blowjob example, is saying "give me a blowjob or I'll beat you so hard you can't get out the door for the next week" rape? She's technically consenting to the blowjob.
Yes. Denaut explained why. Violence, or the threat of violence, takes away consent. However, nothing else does. And I think this is where some young women get preyed upon and then get angry afterwards. They will fall hard for a guy, and they may not enjoy a sexual activity, but the guy will say "Well, I'm going to break up with you without X". So they end up doing it, despite not enjoying it. I actually knew a woman in college in this same exact boat; whose boyfriend really liked anal and he essentially told her she needs to do it, or they were not compatible. What ends up happening? She spend the better part of my Sophmore semester over my girlfriends house, crying about how mean he was for making her do that...But she loved him and didn't want to leave him. When he eventually broke it off with her, she told my girlfriend "It was like he's raped me for 3 months and now he's going to get away with it".
In her mind, she was trading rape for love. But in reality, while the guy was a prick, he
wasn'traping her. Now, I agree with you; she has every right to tell everyone he was a prick. But that ends where she says it was rape. Feminists are going to need to deal with the fact that sexuality is something both shared AND traded in a relationship. Women and men tend to have different levels of sexual desire; it's not a bad thing that sometimes a woman will give a guy sex in the same way that a guy will see a romantic movie with her--as in she may have not decided to go do that on her own, but she's willing to because he did X for her. The real core as to whether that kind of "trade" is healthy is whether or not she still enjoys doing the act of kindness. Most guys don't enjoy romantic movies, but they enjoy going WITH their wives. If a woman is in a relationship where she hates every moment of that "trade"; and feels like she is suffering through it? She needs to be the one to be a grown up, realize it's not healthy and move on.
Men aren't mind readers. Society shouldn't expect them to be. This does create a gray area for assholes to take advantage
butit's far easier to just have women start acting like adults and telling those men to fuck off, then it is for full scale institutional change to punish people who may be assholes, but not criminals.
