Then --- respectfully --- you have never heard him speak in favor of Donald Trump, and you should go watch his speech before arguing about it. It's pretty scary. Maybe after seeing it, you'll understand the vehemence of the anti-Thiel sentiment.

I re-read his transcript before I published my comment. He says he's from Silicon Valley (which is true) but not that he speaks for Silicon Valley.

No, that is not all he says about Silicon Valley. Read the whole thing.

Re-read. "We don’t accept such incompetence in Silicon Valley, and we must not accept it from our government." I think using the word "we" is the closest he gets to your interpretation, but even here it's clear to me that his views are his own.
