Is Racism Worse Then Murder? Should We Have Thought Police And Arrest Racists For Their Thoughts?

I was wondering, do you think it is worse to be a racist then a murderer? I think it is. Murder is not right, but thinking or saying saomething racist surely must be worse then actually murdering someone. Also, when are the police and F.B.I gonna start kicking doors down and arresting people for racist thoughts? Shouldn;t it be a crime to think in a way that dosen't agree with current political opinion? I figure we could send them to Alaska and have them stay in a prison there. Lastly, shouldn;t people who disagree with Obama's policies be arrested? After all, Obama is an African-American, and it is so obvious that anyone who finds fault with him must be a neo-nazi or a KKK member. Why can;t we just arrest them and shut their racist KKK mouths?
