Give them time to quit spazzing out. Probably there's at least one in the group who's at least curious. Bide your time and let them bring the subject up again, preferably when you're in a one- on- one situation away from the more hysterical anti- gun ones. Offer to take them shooting. Before you know it, you'll make a convert.
