He's not telling you how to feel, he's stating why he thinks Obama is ahead. By your reasoning, anyone who says (for example) "Hillary may have lost because Mark Penn ran a bad campaign" is also telling you how to feel? I mean, the two have nothing to do with each other.

Taken another way, one could interpret your comment to mean, "I don't care what anyone says, Hillary lost because of sexism, and denying that is sexist in itself."
