John - I humbly suggest you get your own blog, where you’re free to say whatever you like. You’ll also then be able to manage your commenters in the way that you feel is just and right. You may even be lucky enough to someday have someone posting under a pseudonym call you “evil” and expect to be taken seriously. When that happens, be sure to come back and let us know if your opinion has changed.

So long as you’re posting words on other people’s sites, you’re subject to their rules. If you don’t like it, you have every right to deprive those sites of your valuable participation.
