Answer 3

Blacks in today's world also need to take responsibility for the disrespect they get. They spit and disrespect ppl, too and in many cases judge ppl. In my opinion as a black person, we have no right to tell anyone how to act or that our ppl shouldn't get involved with ppl outside our own because we don't know how to act or act properly in the 1st place. 2nd because of our history. We were enslaved by our own before we ever even knew of the U.S, then we became slaves to white. Now we're just a race that seems to get worse with every passing second. We have absolutely no respect for ourselves. We have absolutely no respect for each other and have absolutely no for anyone outside of our own. We seriously need to learn some respect before we can ever gain any from anyone else. BLACK PEOPLE, GROW UP OR YOU WON'T MAKE IT LIKE YOU THINK YOU WILL!
