Sometimes the people you do business with have political opinions you don't agree with. The melodrama over Thiel's political opinions is pointless. If you demand Thiel steps down, are you personally just going to stop doing business with 49% of the country that voted differently?
Personally I lean liberal, but I'm pretty disgusted with all the theatrics I've seen in this election from the left. The Trump phenomenon arguably occurred because half the country felt ostracized and decided to lob a brick through the window of washington in the form of donald trump. Maybe we should all get to understand our neighbors instead of doubling down on us-vs-them tribalism.
