Legal age for drinking over here is 16. Partying without supervision happens as well. A Lot.
Rape? Not really problems with them, some groups and culture *** under suspicious circumstances happens, and attract the participants, but RAPE is RAPE. Incidentally it might happen. No matter the circumstances. Rape is rape.
How you see it: RESPONSIBILITY. For f's sake. You can teach 12 year old children to be responsible, heck, even younger. Don't blame it on anything, but the lack of responsibility.
You want to drink. Do it responsible. Meaning don't get shitfaced(damn, who in their right non-boring depressing life would want that anyways?)
And people drinking, and your actions are two different ffing things, if a woman drinks too much, she need to sleep, not get raped.
People blame everyone for everything. Truth of the matter, blame yourselves, if you have to blame anybody.
Guys should be better off start thinking with the brain before the ****. If not, do humanity a favor, and cut them both off.
