The original article which sparked this issue (http://dancerscode.com/blog/why-the-open-code-of-conduct-isn...) states that CoCs will cause people to censor themselves out of fear of offending people.

I think this is fine. You should think about how you will make people feel and how people will interpret what you say. And this is good for you, too. By empathizing with the listener, you can find more diplomatic and effective ways to communicate. You'll reach more people.

And if you can't think of a way to do that (which I think is unlikely in most cases) then maybe your thoughts deserve marination and should be shared later, or perhaps not at all.
