She probably thought that she wouldn't actually get caught. Why anyone would want to have sex with a minor is beyond me. I think that it's sick and twisted.
I don't think that this Subreddit picks on women it just picks on the ones who do really bad things to men and think that they won't face any consequences. Some of these women think that they can do certain things to men and get away with it.
I really hope that you don't actually believe this violence is never the answer no matter the gender and besides any man that hits a woman is totally out of line. They are other things that you can do without being violent but that's just my opinion.
