That’s why I mostly use pseudonymous channels these days, like this one. I treat everything I say with my real name like I’m publishing it on the front page of the New York Times and submitting three copies to the Library of Congress.
Many fewer of my current associates hear any real thoughts of mine compared to 20 years ago. I used to get into all kinds of arguments like Stallman’s, on public email lists, which thankfully haven’t surfaced online (yet).
