I have to explain the difference to you? Kamala Harris was a Senator like all the other questioners and should have been afforded the same latitude to ask her questions and not be cut off by her colleagues and later Deemed "hysterical" by those same colleagues. Betsy duvos was an actual Witness,  and Witnesses are interrupted all the time by questioners,  and the Witnesses are not later deemed to be hysterical.  Now certainly the questioner may be considered rude and insensitive to the witness , but this does not constitute sexist Behavior, as this rude and insensitive behavior is applied to women and men Witnesses equally. if you don't see the distinction in these two scenarios then you obviously need to refine your analytical skills and save your bloviating for your friends and relatives. Until you can stop analyzing Behavior through the prism of the left or the right then you're wasting all of our time
