Of course not.
Most of us here at Free Republic are posting anonymously.
And yes, there is no problem with accepting that someone has written an account anonymously. That is something to keep in mind, as I said, but people can lie under their own names, or assumed names that one doesn’t even know are false. If one writes an anonymous account, and there is something in it that authorities want to check into, or it attracts great notice, then they may lose their anonymity. If not, then I will simply consider what’s said on what can best be determined to be its merits.
So are you saying you categorically dismiss anonymous accounts only for being anonymous?
Again, what about the posters here? Many people tell personal stories related to the articles. What about those? Do you dismiss them all because they’re anonymous, too?
And there was “Primary Colors,” a book on the Clinton administration that was originally anonymous. I never read it, but if I had when the author wasn’t known, again I would have just taken his anonymity into account in evaluating his claims.
