Now that's odd: Over on facebook, I find that I cannot comment or even "Like" your posts. (on https://www.facebook.com/Antitheists
) I find it hard to imagine that I could have said anything sufficiently offensive as to be banned. (And it's hardly likely that I'd try that hard! ;-) I'd have to guess that some defensive measure you've taken to protect yourself from religious extremists and other haters has had this unintended side effect.
What I had in mind was a supporting comment to your "An armed population..." facebook post, saying that my government (the US) has proven quite effective at crushing entire small nations with military might. So, and historically, a few dozen (or even several hundred) guys with guns trying to "fight off the government" has never been a problem for them. Check the history books: The Civil War was not the only revolt. Not by a long shot.
