Not that I have any trouble with commenters at all on this blog (not enough traffic I guess), I think I’ll adopt this commenter policy, because it says all the right things.
My favorite part
4. Freedom of Speech: This blog is for my freedom of speech, and mine only. I delete comments that irritate me for more than a few seconds because it is not worth my time to be irritated at assholes on the Internet. This does not curtail your freedom of speech because I am not the U.S. Government. The first amendment of the U.S. Constitution does not guarantee assholes a platform on my blog.
That, my friends, is the correct answer to the question of “Free Speech” on the interwebs.
