Comments on HN is an example of how this cooling effect works. It takes only a few upset readers to take your comment down, so if what you say deviates even slightly, by 0.01 sigma, from the boring mainstream viewpoint, you'll upset at least a few readers.

Same idea, but from another angle. It's well known that you can say a lot in a small group, but very little in a large group, because it's a lot more likely that someone in a 1,000 person conference will be offended by your words. With internet and social networks, you have to assume that you're always talking to the entire western world, and there's a nearly 100% chance that some angry activists will be offended, so you always have to calibrate your talking points to the most boring mainstream viewpoint.
