Saying it's easier to talk about things in China vs US. I've been to China and you can get thrown in jail for saying the type of things we say re. our political environment. My friends there have to speak in whispers in public while people in SF have no problem raging about our politicians.
And saying we should "allow people to say disparaging things about gay people if we want them to be able to say novel things about physics". At its least a really poor choice of words there. The choice of words makes it sound like it's okay to stand aside while they spout bigotry. Perhaps he meant it's okay to say it, but we should argue against it - but unfortunately for him that point was not made because the intention of the article was to support free speech. Bad example.
