I think it's stupid to make business decisions based on just that (of course, the content of the speech matters - e.g. if you are a coal miner and the speaker says she will bankrupt coal miners, it's prudent for you to exercise extreme caution in dealing with such person). But that's not where we are at. We are at people trying to shame YC into making business decisions they obviously don't want to make based on shaming mob's political preferences.
