There's certainly a line where someone stops being "just" a supporter and becomes something more. E.g. a big complaint against Brendan Eich was that he wasn't just anti-gay-rights, he actually contributed money for the Prop 8 fight. The big question is where that line should be drawn. You say Thiel is a Trump surrogate, but I'm not so sure. Then again, he did donate a substantial amount of money in the last few days, so maybe he really is close enough to the campaign to act as a surrogate, especialy since he is being explicitly given as an example of someone from Silicon Valley who is supporting Trump. It's a hard question - I'm not sure, personally. "You cannot coherently oppose Trump and support Trump's political campaign." Well this part I don't really agree with. A big part of democracy is coherently opposing other people's ideas, while not opposing their right to voice those ideas.
