Why all the blogs about racism?

I've seen quite a few posts about racism in the past couple of days.  The only one that I can really remember reading only said things that are ridiculously obvious to me and should be to everyone else.  The blogger wrote that "Racism is staring YOU straight in the face!"  or something like that ... well, DUH.  You don't need to tell me that.  I live in East Texas, and down here you are constantly reminded that some people don't care for people of another color.  I'm not just talking about whites, I'm talking about blacks too.  Listen to some white people talk (the majority of them are probably older than 30)  and listen to groups of black people talk among themselves.  Black people have told me that they hated white people or done something that showed they didn't like whites right in front of me.  Anyway, my point is that you don't have to be a rocket scientist to know that racism is a huge part of our society.  Everybody thinks that our current President is so racist because "he didn't send help to New Orleans fast enough."  I don't really understand how you could be the president of a country so diverse and be racist at the same time.  I find that accusation to be completely ridiculous.  Well, this post isn't about that topic, but I think that people need to stop accusing other people of being racist and need to start trying to figure out what they can do to make their lives and the people's lives around them better.  Yes, racism exists (duh, if you haven't figured that out then where is your brain?), but you don't have to be a part of it.
