It is insulting, because it asserts that those who supported someone else this year were driven by low prejudice and mindless bias.
It is manipulative, because it asserts that if you want to be understood, both within the community and in the larger brotherhood of man, to be wholly without bias and prejudice, you must support Mrs. Clinton.
It is not true. Tough hill-country men voted for her, men so backward they'd give the lady a chair in the union hall. Tough Catholic men in the outer suburbs voted for her, men so backward they'd call a woman a lady. And all of them so naturally courteous that they'd realize, in offering the chair or addressing the lady, that they might have given offense, and awkwardly joke at themselves to take away the sting. These are great men. And Hillary got her share, more than her share, of their votes. She should be a guy and say thanks.
It is prissy. Mrs. Clinton's supporters are now complaining about the Hillary nutcrackers sold at every airport shop. Boo hoo. If Golda Meir, a woman of not only proclaimed but actual toughness, heard about Golda nutcrackers, she would have bought them by the case and given them away as party favors.
It is sissy. It is blame-gaming, whining, a way of not taking responsibility, of not seeing your flaws and addressing them. You want to say "Girl, butch up, you are playing in the leagues, they get bruised in the leagues, they break each other's bones, they like to hit you low and hear the crack, it's like that for the boys and for the girls."
And because the charge of sexism is all of the above, it is, ultimately, undermining of the position of women. Or rather it would be if its source were not someone broadly understood by friend and foe alike to be willing to say anything to gain advantage."
