Thanks, Marco, for drawing my attention to Sam Altman's great blog post. More people should take Sam's attitude:

The way we got into a situation with Trump as a major party nominee in the first place was by not talking to people who are very different than we are. The polarization of the country into two parallel political realities is not good for any of us. We should talk to each other more, not less.

We should all feel a duty to try to understand the roughly half of the country that thinks we are severely misguided. I don’t understand how 43% of the country supports Trump. But I’d like to find out, because we have to include everyone in our path forward. If our best ideas are to stop talking to or fire anyone who disagrees with us, we’ll be facing this whole situation again in 2020.
