Rule #1 Don't be racist. Not even a little bit.
It can get you in serious trouble. If you are racist on a street, gangs might get you. If you are racist at your job and you work in PR, you will have big problems on your hands. If you are even kind of racist you can get yourself not elected if you ever want to run for office. Even sometimes powerful comedians do a little racism and it brings about their demise. So I say don't be racist, don't even try it.
I think the most important reason to don't be racist is that someday you will probably want to be on a reality show. Even though you are not there to make friends, and even though some of your best friends are from races, you don't want to be even a little bit racist. Because once someone calls you a racist, you are done. You are the bad guy on the show, and you live a sheltered life. Trust me on this IT"S NOT WORTH IT.
So I am going to try to give some tips on how to don't be racist.
