Protecting Obama?

CBS News has decided to not allow posts anymore in response to stories about Barack Obama because of the racial slurs that seem to be following. It's really quite sad that the media needs to censor parts of it because of the comments that some people make. But once again we get into First Amendment rights. Blogs, wikis and such allow people an outlet for speech. Perhaps it is the anonymity that makes blogs so troubling to people. So where do we draw the line? Do we allow hate speech? This country was supposedly founded on the right of free speech, but what happens when we don't like what that speech is saying? Most people agree that hate is a negative, unproductive emotion, but since we are all different human beings and have differing views, it becomes difficult to limit certain types of speech and not others. Blogs are open forums and although they are limited in certain ways structurally, the ideology behind them is free flowing information. If we curb that information, aren't we altering the structure of blogs, the very thing that makes them unique?
