Sometimes the responses write themselves. The response to this is a case in point:
Guns are useless, especially handguns. But I’m not that ignorant: I know that gun control is a lot like health care–everyone knows it’s a good idea, but we really don’t want it to cost anyone their “freedom” (or worse, their money!).
Apparently he is that ignorant.
I would like to suggest he ask the next police officer why he or she is carrying a useless handgun and then read up on what “everyone knows”.
