This is all rather scary.

She is a vicious clown, an overacted parody of that which she purports to be. The best way to deal with such a person is to play up to her many many faults and make of her a figure of fun. A caricature so ridiculous that for the majority even claiming to believe in her "nutty" ideals makes you seem an idiotic fool too.
Taking her seriously lends her credibility, something she does not deserve.
It has worked before, Sarah Palin is recalled as nothing but a joke a woman who hunted wolves from a helicopter, Christine O'Donnell is only recalled as the loon who believed in hybrid mouse people and had sex in a grave yard because she thought she was a witch. Matthew Whitaker, the grifter who sold toilets for men with big dicks and big foot dolls. And of course the "my Pillow" "my mustache" guy.
You give these idiots enough publicity rope and they will hang themselves with it. Just keep pointing out this racist fuck is the same one who advocated (Insert stupid thing they actually did here)
