“It’s possible we have to allow people to say disparaging things about gay people if we want them to be able to say novel things about physics,” he wrote in a blog post this week.

In that post, he said he felt freer to speak his mind in China: “I realized I felt more comfortable discussing controversial ideas in Beijing than in San Francisco.” He also said he is “now seeing many of the smartest people I know move elsewhere” because they feel stifled in the Bay Area.

Think of it as the perfect cherry on top of Silicon Valley’s year of culture wars, from Peter Thiel’s support of President Trump to James Damore’s famous Google memo to all the sexual harassment scandals.
