Whats with this attitude that black people are invincible that everyone seems to have?

People on here imply that you cant mess with black people or you will end up dead, or if you pick a fight with a black person you will automatically lose cause you are white and will lose regaurdless of your size and skill. Ive beaten up black people, ive made racial slurs, and im still alive arent I? what makes black people so tough? and it really p*sses me off white people on here have this attitude.
