Rosie O'Donnell is not racist, despite what Youtube might say. Her umpteenth rehashing of the classic "Yackity yackity shmackety Hostess Twinkie gibbety gibbety mish mash" joke is only being posited as racist because of a) Michael Richards and b) the continued existence of Youtube in a post-Michael Richards world.
Rosie could have substituted 'Chinese' and 'ching chong ching' with 'Spanish and lots of 'rrrrrrrrrrrrrrr' or German and 'glochen Schprockfluschensproinkel" with no repercussions. In a Youtube free world the joke would have passed unnoticed.
I almost hope that Youtube and its ilk are sued out of existence, because in the event that it does not disappear, Youtube presents two possible courses for the future of our society. Either people are going to get a little more thick-skinned and reasonable in their responses to things that offend them (not gonna happen) or people are going to have to remain extremely guarded all the time for fear that a captured faux-pas will cause them to be banished for ever (almost certain to happen).
