Being a man, as well as very liberal, I have to agree with you that this kind of nonsense is idiotic. That being said, please put your big girl panties on, because your manhood is not being attacked. If this is a liberal 'War on Men', then you probably also think that the separation of church and state is a War on Christmas. Feminists feel that it is necessary to change the terminology that they feel subtlety, yet unequally reinforces gender preferences. They fail to realize that the term, man, can refer not only to gender, but is also shorthand for mankind, and thereby can connote even an individual. I don't particularly care to say personhole cover, instead of manhole cover, but hey, if they hate manholes, let them say asshole covers if it turns them on.
The rest of your diatribe... you gotta admit might be construed as a bit sexist, huh? Men built this world, yet your own mother didn't produce anything valuable? I wouldn't stick with that argument. It is sorta self-defeating.
