This is a great thread!
On one hand, I really find the "alpha" male wannabe, asshole type of exaggerated masculinity to be ridiculous.
On the other hand, as a fairly large, Neanderthal type, hairy bastard, who happens to like to do some things that are considered "masculine", I laugh when people with this strange bias against masculinity automatically categorize me as something that I'm not. A couple that I was building a house for, were shocked to realize that I was spending my lunch breaks playing with their kittens, lol. They ended up naming one of them after me...
I don't feel guilty for being a male, and I don't feel like less of a male for going to the ballet, opera, or loving to cook.
