"I am who I am because I was adopted"....
Phooey - I say to that. You are who you are because you choose to be that way. I know there are some genetics that are passed on from your DNA. The way you look, how tall you are, your taste buds and smell etc......but much of your personality, many of your mannerisms, a lot of your attitude is passed on by who raises you and your environment.
You can boo hoo all you want and be miserable and blame adoption....but you really have to blame those things on not adoption itself but who adopted you, your relatives, your friends you chose. And much of people's bad attitudes can be turned around. Instead of living in the past....they should look to the future and what they can accomplish. What's done is done and it cannot be reversed. What is the point of dwelling in it, wallowing in it?
Be positive, fight for change but I cannot stand the depressing rhetoric over and over.....give it a rest.
