I did this all the time. Some girls just don’t have female friends. Someone like you would’ve seen me walking off by myself with a group of 8 or 10 guys and thought ‘stupid stupid stupid’, but odds are those 8 or 10 guys were my friends. Course I also went to parties by myself, would leave my drink on the bar at the Beehive while I went to the bathroom and know that Corri would let me know if anybody stuck anything in it.
One time did I trust the wrong person, and it took a year and a half for him to show his ugly side. All in all, not a bad record.
There is a difference between reasonable precaution and overzealous fear. If you think that not taking the bus at night was a reasonable precaution for you, that’s fine. But many others of us (myself included) used to walk three or four blocks over to East Liberty from Shadyside and ride the 71C Wilkinsburg to work at 11:30 at night without thinking of the danger. That doesn’t mean we were wrong, either.
And then some of us would get dressed up all slutty like and go to a party with the blatant intention of finding a guy to hook up with for the evening that we know will never call again and won’t bother us. 
Unless your intention is to get laid, right?
Because it generalizes men as dicks with legs that only want to get laid and makes someone believe that any man will rape a woman if he’s drunk and horny? It’s a pretty misandrist statement. And it ignores the fact that there are plenty of women who are out at the party to just have a good time with whoever they might hook up with that night.
And what should they do about it? It’s not possible to make society perfectly safe, so there’s no way we can stop people from choosing to live their lives in a way they are comfortable with.
They’re not, at least in my experience, any more eager for sex than drunken young women. The difference is, when a drunken young guy wakes up and regrets sleeping with whoever he slept with, he gets razzed by his buddies a lot. When the drunken young woman wakes up the next day and regrets it, she has feminists telling her she was raped.
By the way, who actually thinks when they go to someone’s bedroom late at night while both of them are drunk that they’re going to play Monopoly? The invite to the bedroom is an invite for sex, not board games and cartoons.
On the other hand, I’ve been an Episcopalian all my life, including my misspent youth, and I’ve never been aware of any problem with rape or felt unsafe although I admit such a problem might be swept under the rug.
