There will always be rude people, no matter how comfortable you are with yourself. I get plenty of positive comments, and am very comfortable wearing my kilts, but I still get a negative comment every now and then. Had some kids call me "fag" from their car the other day, and when I went to Old Navy for a couple t-shirts yesterday, turned around a few times to catch people pointing and snickering (How rude!). It wasn't because I was "insecure or uncomfortable" or looked funny; I was feeling great, and I had several beaming compliments earlier.

But, by and large, the negative reactions are found only where dumb people congregate (like malls), or when people are just trying to find someone to irritate from a safe distance. I never get rude snickers or comments walking into a pub, restaurant, museum, or vancouver...
