You misunderstand the point of this conversation. I am not claiming any kind of qualification for instructing you in any subject. I do submit that you would be much happier in a more open society, so if you are still open to instruction, I suggest another term of study in the U.S. Let me know if you need a letter of recommendation.

As regards my willingness and ability to wave a gun at someone who can wave right back, the traditional venue for its exploration is a challenge to a duel issued on rec.arts.books. Then again, since your government doesn’t trust you with sidearms, perhaps you would be better off waving something else.
