I think most of what's needed to understand it is in the insane tweet itself.I genuinely can't comprehend this. And not because it's Trump, but the hero worship of politicians in general. The idea of stanning for someone who would never ever do the same for you is simply unfathomable to me.
She can't stand the "lie" spread about him, ie everything bad she heard about him are all false in her echo chamber.
Most un racist man, ie if she act like him, she's not racist.
In secret love him too, ie she's normal and part of the majority, everybody is just hiding the fact that they all love him like her so she's normal and courageous to speak up.
She want to be an awful person and be respected for it and not suffer any consequence while also considering herself a good person. Someone like Trump becoming President means she can be her awful self and that a lot of people also think like her and so won't judge her.
Also she was probably drunk, half of this make no sense, what does "tool" refer to here?
