Being the odd one out can be an advantage, so don't get upset if someone calls you out and makes you feel weird for doing something you thought was the right thing to do. Whoever is trying to push your buttons simply doesn't know how to peg you or figure you out, and they are being lazy in trying to understand you. They're too busy following everyone else and doing the 'in' things to think independently like you do, but you shouldn't let their jealousy bug you.
