Have we fallen so far as an "open society" that the left feels justified in making a company who hosts stores for thousands of other companies "defend" themselves for doing business? I'd rather they have to "defend" themselves for NOT allowing Breitbart a store. What happened to freedom of speech? Is it only supported if they agree with what you are saying? I thought the people who called for all businesses to boycott YC simply because of the political donations by Peter Thiel reminded me of witch trials.... truly sad.
