I agree, the fear that a C&R holder would be singled out somehow is paranoia. It's the best tool for collecting and a hell of a deal for a little paperwork. But, as has been said, fear and ignorance go hand in hand.
Way off-topic, but the English situation is awful. Next, they'll try to ban kitchen knives. Makes me wonder if the riots that happened last year would have had a difference outcome if a good portion of the population was armed. The supporters of concealed carry always point out that crime goes down as gun ownership goes up. Maybe gun ownership in the U.S.A. why nobody is trying to occupy my front yard?
