It has been my experience that most Men's Rights Advocates are whiny little children that have been burned by a bad relationship or two and thus have concluded that all women are evil harpies just out to get them.
My experience with women has been much different.
Maybe that is why I am not a whiny, self-absorbed asshole like the folks at http://exposingfeminism.wordpress.com, http://www.avoiceformen.com, or http://www.the-spearhead.com
Or maybe I am just a sane being and don't feel the need to blame someone else for all the troubles in my life.
