> But I care about people trying to be morality police and discouraging someone blogging on their own website from writing rudely and writing politically incorrectly

This appears to be a strawman. You already admitted he violated the CoC - so he is in the wrong here.

I'm not sure what else there is to disagree with - that's been my assertion from the beginning.

If he wants to write childish stuff on his own website that is not covered by the CoC, that's his choice. I'm also free to express my opinion on that, but I never implied that he shouldn't be able to write whatever he wanted on his own personal blog.
