He funds longevity, seasteading, and promotes people being definitive in their goals and working on things no one else is. He also personally funded the hunt for justice against an evil rag hiding behind genuine journalistic protections.
If you're on the wrong side of an issue from Peter Thiel, it's not because he's being reflexively contrarian, it's because he could write a 100 page thoughtful essay on why his position is better than any alternative.
The reason that Peter Thiel seems so contrarian is because so many other people are so cowardly. Shouldn't more billionaires be crushing bastards? Shouldn't more billionaires be funding medical research? Shouldn't more billionaires be publishing books to motivate the masses to create themselves the future that has been only dreamed of for the last few decades?
On the short list of people in this world who are doing a really really great job with what they have, Peter Thiel is at the top of my list.
Now the caveats. Violations of the 4th amendment suck, and if Palantir is part of them, it's not great. Trump is clearly not the best the business world had to offer. Christianity, not so fabulous.
I consider the man a legend and hope to see great things from him.
