It's possible? Not saying you're wrong. But I do lean more towards it's a blood purity thing. They don't like people who think differently. They don''t know how to make us think like them, and they don't feel safe unless everyone is thinking ilke them. Eugenicists are driven by fear. Fear of people in power not being white. Fear of majority brown nations. All kinds of other racist shit. And ableist. And queerphobic. Misogynistic. And so on.
It's about bigotry. They can't cope with seeing people they have convinced themselves are inferior outworking and surpassing them.
There has to be a sinister someone behind them, helping them out, because we all know that the white man is supreme!

No. His grandfather's mediocrity produced DJT's father, AND somehow his intelligent son too. And DJT got none of the smart bits.
It's why I think he was drawn to Nazism in tthe first place. He believes he has better blood than us. Like a king. That he was destined to rule.
They appeal to his ego, so he swallows it whole.
