I'm male, but very different from the males around here. I don't hunt, don't like NASCAR or watch sportsball, I dislike violence on TV (much less perpetrate it), I don't harass or denigrate women or minorities, don't like getting drunk, don't find willful ignorance to be a source of pride, I don't litter or drive like it's a competitive contact sport, I don't "dip" snuff, I'm not loud, aggressive, or belligerent, I don't cheer when we bomb defenseless Third-World countries, guns don't give me a hard-on, and I find rabid nationalism and shallow plastic patriotism repugnant. I can't even imagine being so insecure as to need to "prove" my "manhood."
If someone considered me to be "feminine" because I'm nurturing, sensitive (overly so sometimes), and attentive to my mate, that would be OK with me, because I don't think being feminine (or a woman) is shameful.
