There's nothing wrong with not wanting ride in -10 temperatures. Personally, I don't like riding below 40. I've ridden in the 30's, but really, it's not fun for me. I have the gear, so when the mood strikes me, I'll take my hybrid out in the winter if it's a sunny day and the roads are OK.
Ice, snow, and tires just don't mix for me because I would be spending the whole time worrying that I was going to crash. Besides, I like having a season for x country skiing and snow shoeing.
But, I don't think anyone is weird for commuting through the winter.
