I mean, I wear my kutte often. It's part of who I am. However, when I do go to places wearing that I don't demand to hear metal or anything like that. I'm perfectly fine with whatever is normal. I just like the way I look when I wear those sort of things. I feel more like myself in black jeans, black boots, black shirt, and my riding jacket. When I wear blue jeans and a non-metal t-shirt (which is what I normally teach in) I feel a little out of my element, but I can't walk into class with a Von "Satanic Blood Angel" shirt now can I?
As far as the metal culture goes. It is silly, but I have a lot of friends from west coast to the east, and beyond, that I enjoy spending time with. There are few things more enjoyable in life than hitting up a 3 day metal festival with a handful of friends I see only once or twice a year, getting drunk with them, and seeing awesome bands live. I don't take the music all that seriously, but I do value those friendships and those experiences more than life itself.
I recently described my idea of heaven after I told a friend what CS Lewis's idea what heaven was like (he said it was reading Italian romance in a garden or some shit) and mine was sitting in a hot-tub with a couple of good friends, several half-naked chicks, a tap of beer or three next to me, and Motorhead playing a few feet away.
