Everyone talks shit about the opposite sex at some point. You're new to this forum so you have probably not read a lot of the posts here yet. Most of the people speaking negatively about the opposite sex (on this forum) are males.
Take the OP for example...she expressed a fear of males but did not speak of men in a negative way.
You are right, women can be just as immoral as men. Common sense dictates this since women are not a separate species from men. The problem is that there are too many misconceptions about women and men in general. I've read one man in particular (on this thread) who says he cannot relate to women. That's obviously because he thinks that women are completely different than he his, than men are. Sure, we do lead different lives but we all have the same emotions and the same needs. I have found myself being able to relate to both men and women. I don't find a man foreign or unapproachable just because he has a penis and I do not.
Female sexual predators are becoming widespread? This has been happening recently in the last decade? I suppose it is the new century. It was about time we caught up to our male counterparts. I mean, is it some sort of new crime wave trend? That's pretty creepy. So do they run around with vibrators tucked into their trench coats? I'm just teasing. I do realize that there are female sexual predators, but I wasn't aware that women rapists are on the rise.
Women have been known as the fairer sex and it's not only women who have been responsible for propagating this false belief. Sure, feminists might want the world to believe that women are inculpable and righteous but that's a whole other animal

. There are men (also women) out there who have a certain ideal of what constitutes femininity and they believe that women should be agreeable and accommodating at all times lest they be shrews (god forbid).
It takes two to tango and women are not soley responsible for gender beliefs and misconceptions even if Western society has been patriarchal for thousands of years and I'm sure it wasn't the majority of women who came up with the belief that women are inherently inferior morally, physically and intellectually. Only a misogynistic woman (yes, they do exist) would say such things about other women. Only a manipulative woman would try to make others believe that she is intellectually inferior or otherwise incapable. What purpose would propagating such a belief otherwise serve?
