For a while now I've been prejudice against my own race.
Why would you feel the need to be prejudice against your own race?
I see too much stupid people in my own race.
People are people no matter what race they are, and even if you belong to the race,  you shouldn't judge people and think they are one and the same. People are stupid no matter the race.
What, saying I'm stupid is racist af. Now everyone is going to hate me because of what you said.
I think you're being overly critical right now, you need to understand is that any type of prejudice is wrong. You shouldn't hate your own race or any race for that fact.
