Klayfish I can respect your opinion, and the following isn't directed toward you, you just happened to remind me of a person of similar mindset, and a recent interaction I had with them.
We have an acquaintance, friend-of-a-friend, that has been at many of our mutual friend's parties. A few years ago, we were at the mutual friend's Halloween party, first time I've met this fella, we get along well, have many common interests, and similar thoughts on a lot of subjects, i.e. we're both more or less nerds. Then the subject of guns was broached, not sure how it started, but at the time I was building my first AR-15, and before I knew it I was being chastised and interrogated by this new acquaintance about my hobby. He was staunchly ant-gun. Not wanting to ruin the party, I said my piece, moved on, and stayed away from the subject the rest of the night.
Fast forward to this year's Halloween party, I knew the acquaintance would be there again. SWMBO and I made it a point to not bring up firearms just to stave off awkward moments and/or confrontation.
We say our hellos, catch up, and next thing I know the acquaintance starts picking my brain about firearms, and is telling me about the handgun he'd picked up a few months back. Say what? Who is this guy?
Come to find out, a series of events in their life had changed his opinion from staunch anti, to having a CCW. Acquaintance's wife went back to grad school, and while there, acquired a bonafide stalker. Full on creeper mode, following her around, to the gas station, to home. Acquaintance and wife are fairly new parents, kid at home, stalker following wife home, scary situation. Police weren't much help.
Additionally, acquaintance found 15 minutes, and then some, of internet fame from a Twiter post that went viral. The post was a harmless, funny anecdote about an unfortunate but humorous thing that happened in their life, shared with friends. Then it got shared again, and again, and the media picked it up, and shared some more, and the comments came rolling in, and things got taken out of context, and the bad comments came rolling in, and folks who shouldn't know anything about them started sharing info they shouldn't have known, and folks started making threats, you know typical internet lunacy.
Anyway, this guy was strongly in disagreement with owning firearms, and now they want to go shooting with us. No doubt the circumstances that changed their mind are unfortunate, but they changed their mind.
