alt Hacker NewsHe is going around talking about biblical prophecies and the antichrist so regardless of whether you consider thiel a Christian or whether he considers himself a Christian the comment you are responding to is entirely accurate in saying he is interested "only in the hate and doom parts of [Christianity]".
Peter grew up in an Evangelical household which probably shaped his framing/worldview. As an adult he still identifies as a 'heterodox protestant'. Which in America usually means he's not really Christian, he just picks and chooses some ideas from it. The way he uses 'Antichrist' to talk about politics and tech (not just a single person or religious entity) seems to confirm that idea.
