Really? People are actually still bothered by crossdressing? Would you have been opposing women wearing pants?
Also, saying that you think it's "weird" or "creepy" or "gross", yet it's none of your business is, I suppose, an improvement, but not much of one. First, somehow I doubt that, despite it being "none of your business", you actually treat these people the same. Second, having some private prejudice doesn't make you much less of an asshole the way I see it, it just makes it less noticable.
TL;DR: grow up.
