I think people that pretend to be another nationality are pathetic?
In my town I've known Italian people who tanned and pretended to be Puerto Rican. I've also known Puerto Rican people who were trying to get as pale as possible and pretend they're one of the white races.
They'll present themselves as the race they wish to be with new people they meet, but then act all surprised when the new people abandon them after seeing their family and finding out the truth.
I don't get what's so bad about sticking to the way you were born. Why change your appearance and lie to people? It makes no sense.
