Three things: 

1. Don't be a bully. If you're having personal issues, hurting others won't help you heal.
2. A lot of people (on Twitter especially) think it's ok to tell someone to kill themselves. It's not. Even if it's someone who has a history of racism and/or bullying. If you have the guts to say something so vile (kys; go hang urslf; drink bleach; ur disgusting i hope u die in a fire), you're no better than that person you're telling to kill themselves. Fact of the matter: some people were raised to be racist. When you've been taught something from a young age, it's hard to unlearn. Have patience with people. Teach them instead of degrading them.
3. I'm not your stereotypical black person. In fact, because of the way I speak and the things I like, people on the internet constantly assume I'm white. I want to clarify that there's no such thing as "not black enough". Im black. Period.

Anyway, i just felt like venting. Can't believe you read this whole thing. Thx though.
