I've long advocated that experienced and diplomatic members of gun clubs and conservation clubs, etc., should invite influential liberals and moderates in their community (including journalists, and politicians) to the range for a day of safe, responsible informative fun.
Follow the safety rules to the letter, no "big talk" (like "blowing away" targets, etc.), relate a touching family anecdote that involves firearms, work your way up from a .22LR through larger calibers, and don't pull any "surprises" or tricks (hot loads, unduly large calbers, ietc.) for a laugh.
Knowledge dispels ignorance, which is often the basis for fear.
