Very clever. At heart they will stand up for their freedoms regardless of wether others think they will have it.
As for the "...what does happen with measurable frequency..." How many CC holders have commited murder or attempted to with their weapon at a university campus? How will banning 6 cosmetic features on a weapon stop shootings? How are gun free zones working out?
There was nothing particularly clever about noting the disconnect between the constant slinging of terms like 'law-abiding gun-holders' and the claims that they will break the law even though they will receive no benefit from doing so.

2) It won't, but stopping shootings is not realistic, nor necessarily the goal.
3) Overall, fairly well, but some occasional ugly incidents thrown in.
