Still no one is willing to name the beliefs that 'you just can't say.' In McCarthyism it was communist/socialist beliefs. What political beliefs can't you espouse in public without being shunned? For Thiel it's probably the pro-authoritarian/pseudo-monarchist beliefs of the neo-reaction guys he runs around with. Gotta be honest, I don't mind those being shunned.
You just named some of the beliefs that you can't say. Basically you agree with Thiel.
One more thing to note: you've called the guy "pro-authoritarian/pseudo-monarchist". Is this how he describes himself ( I guess no )?
I grew up in a country with strong far-right culture. Nazis are calling themselves nazis.
Peter Thiel himself doesn't describe himself that way but the people he pays attention to explicitly do. Here:
Yarvin told Yiannopoulos that he had been “coaching Thiel.”
“Peter needs guidance on politics for sure,” Yiannopoulos responded.
“Less than you might think!” Yarvin wrote back. “I watched the election at his house, I think my hangover lasted into Tuesday. He’s fully enlightened, just plays it very carefully.”
and then combine that with the fact that Yarvin calls himself a Jacobite and you've got the monarchy/authoritarian connection.
The Thiel thing goes a whole lot deeper than Damore or some of the other common examples of "SJW" pushback.
