It is impossible to adequately address why some male and female HRC supporters do not want to support Obama if he becomes the nominee without addressing the hate speech his campaign inspired and has done almost nothing to stop.

A few examples of hate speech:

It is ludicrous to assume that the Obama supporters can viciously attack women and girls for months, vicously attack our gender, and then assume that we will be happy to support Obama. That's not logical and although both sides have some supporters who are prejudiced, the direction of prejudice apparently is almost entirely one way:from the Obama supporters towards the HRC supporters.

Obama must address the extreme hate against women his campaign has fueled, he must apologize for the abuse his supporters inflicted on women  and girls, and he must take concrete actions to stop the hate speech in order to even begin to heal the wounds his supporters have inflicted on people who happen to be born female.
