"I've been struggling with how to respond to the President's tweets and posts all day. Personally, I have a visceral negative reaction..."

"... to this kind of divisive and inflammatory rhetoric. This moment calls for unity and calmness, and we need empathy for the people and communities who are hurting. We need to come together as a country to pursue justice and break this cycle. But I'm responsible for reacting not just in my personal capacity but as the leader of an institution committed to free expression. I know many people are upset that we've left the President's posts up, but our position is that we should enable as much expression as possible unless it will cause imminent risk of specific harms or dangers spelled out in clear policies... These are difficult decisions and, just like today, the content we leave up I often find deeply offensive. We try to think through all the consequences, and we keep our policies under constant review because the context is always evolving. People can agree or disagree on where we should draw the line, but I hope they understand our overall philosophy is that it is better to have this discussion out in the open, especially when the stakes are so high. I disagree strongly with how the President spoke about this, but I believe people should be able to see this for themselves, because ultimately accountability for those in positions of power can only happen when their speech is scrutinized out in the open."

I strongly support this commitment to freedom of speech, and I'm glad to see the theory of freedom of speech articulated clearly where lots of people will see it and maybe even believe it.
