I'm troubled be people who can help their condition but either are emotionally unable to or for some reason think it's okay.
Case in point:
Scary link to Madonna
Those who cannot help their condition get nothing my sympathy. Being repulsed by those who are physically malformed is something people generally get over when they know people afflicted and understand it's never an accurate reflection of who they really are. I also personally see it as a sign of maturity, but that's just me.
