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.

Its ironic because he was homodoxxed by Gawker
