Browbeating, yelling, saying "neener neener the Second Amendment (WWJMBD?)", won't really help to win people over; indeed, it will reinforce the mass-media driven stereotype of the firearms or self-defense enthusiast, and they'll redouble their conviction that those guns need to be banned. One catches a heck of a lot more flies with honey than vinegar.
Stupidity is trying the same thing over and over, and expecting a different result every time.
"One catches a heck of a lot more flies with honey than vinegar."
I'm not interested in catching flies---I prefer to kill them.
