How come I really hate my ethnic identity?
That's sad because why would you hate your ethnic identity?
I had my DNA checked, I thought being Jewish was kind of boring.
Having your DNA tested can definitely be interesting. It shouldn't change how you feel about yourself, though. Be proud of who you are!
I just wish I have something other than Jewish.
Jewish people are cool, just like every other race. Be proud and hold your chin up high because that is who you are and your ancestors would be really sad if they knew you were not proud of your heritage. You are actually one of the coolest Jewish people I know.
