I think A Tribe Called Quest said it best:

"You looked in the mirror, didn't know what to do
Yesterday your eyes were brown but today they are blue
Your whole appearance is a lie and it could never be true
And if you really loved yourself then you would try and be you"

I think a lot of people take this route because they think its the only way they can feel better about themselves. I think there are much better ways out there. Either way that's just my philosophy. I voted don't care. Nobody's forcing it on me, so its not my issue.
