Peter Thiel has always been a controversial character in Silicon Valley. But his backing of Trump (and a recent follow-up donation to his campaign) has some techies calling for him to be ousted from board seats at companies like Facebook. Slate’s Will Oremus asks: “Should a prominent Donald Trump supporter be allowed to continue holding positions of power in the Valley?” (I don’t have much in common with Peter Thiel. But calling for people to be fired for making political donations isn’t the path we want to take.)
