That is an opinion, not a fact. Personally, I don't feel that I have to stick doughnut-sized (and shaped) chunks of wood through my ears to express myself, and those who do are just asking to be criticized.
Be honest, if I walked up to you one day (as a complete stranger) wearing platform boots, broken glasses, and a chearleading outfit (I'm a guy btw), would you seriously not have any urge to judge me? When you intentionally make yourself look abnormal, you are going to be criticized, so if you can't take the criticism, then why do it in the first place?
Btw, saying that what people say is unimportant, then proceeding to post your own opinions makes you sound a little egocentric...
