Well the alcohol thing is mostly so that people aren't going to get other people drunk to make them consent. I can understand it up to a point.
Woman chooses to go out, have a good time, have a few drinks
Society tells her she can no longer consent for sex she may want because of said drinks
Why is society dictating to a woman whether or not she wants or should have sex or not?
Because of asshole guys who put their dicks inside of women who have drank so much they pass out.
Thats not the same as a woman who only got a little tipsy by choice and wants to engage in sexual relations with some random. She should be free if thats what she wants. However at the same time, one is resposible for their choices. You cant complain the next day that what you chose to get up to is someone elses fault. If I got drunk and lost money to a casino, I cant get my money back. It was a poor choice on my part and I have to accept the consequences
We are essentially trying to have a system where you cant touch a women if they don't consent (which is fair enough of course). But if they have had any alcohol to drink, they cant legally consent. But at the same time, if they do end up having sex, it's ALL the males fault and its now a matter of rape if the woman wakes up with regret. We are not allowed to chastise the woman for her poor choices (victim blaming) and we free her from the burden of responsibility of those choices.
Despite the fact that she could have been fully conscious and initiated the flirting, leading and engagement for sex (Shock horror!
A woman that's into having sex!), the male could have his career destroyed because she wakes up and 'changes her mind' in retrospect (must be that male privilege we are so used to hearing about).
