(and I know that writing this here does meet with David Codrea’s contempt, as I blog here anonymously)Not at all, and I apologize if anything I said led you to believe that. I actually wanted to leave a comment, but they're closed on the linked post--and now's probably a good time to clear this up, what with the doings of recent days.
Like anything else, it's a choice. Those of us who have made it know full well that it carries a cost in terms of reputation, career options, etc. But I honor the spirit of Publius, and believe that anonymity can be a key guarantor of freedom.
What I have contempt for is not anonymous blogging, but those who abuse that anonymity to troll and insult without any personal accountability. I believe in their right to do so, understand, but I think it's unethical and cowardly, and have no respect for them as individuals. I have a pretty simple rule--I never expect anything out of another that I'm not willing to do myself. As such, I have never said anything to anyone on the Internet that I would not have said to their face, with their full knowledge of who I am. Which means I will accept real and personal consequences for my words and actions.
