Peter Thiel espouses eugenics, consistent with the white South African childhood he lived, an experience he shares with South African Elon Musk. Like Musk, both espouse viscious racist anti-immigrant beliefs (about spoiling the pure blood of America) even as both are naturalized citizens who were non-US immigrants to our country.
Thiel is a traitor to our beliefs as a nation of immigrants whose founding motto is "e pluribus unum", a belief he's too stupid and arrogant to understand.
