"Why is it sexist when men interrupt Kamala Harris, but not Betsy DeVos? "  The answer is, it's probably not sexist when men interrupt Ms. Harris or Ms. DeVos.  It's just rude.  As it is when women interrupt men.  Let's all dial back some of the '-ism' rhetoric and start by bringing back manners.  That may go a long way in helping to heal some of our divisions.  Then we can work on the '-ism's'.  Thank you.
