Oh, yes. I found the "This page is intended for the benefit of urban conservatives who get to reading about firearm issues on conservative forums such as FreeRepublic, and decide that in order to be a true conservative, they will have to buy a gun, despite not really knowing anything about firearms (and for people in similar situations)." article to be quite interesting.
Quite frankly, if you are going to argue for anything on an online forum, requiring anyone to BUY your own book isn't really the best way to get a good dialogue going.
