I have kids. There has never been a time in their lives when there weren't guns in the house. They just accepted them. When they were old enough they learned about gun safety. When they asked why I carried and had guns in the house, I just told them the guns were for protection. Now, my girls are 18 and 20 and want to carry, themselves.
I haven't ever been hassled. In fact, the only interaction I've ever had was a local cop asking how I liked my Sig. No civilian has ever said a word, but then, I'm 6'6", 260 lbs, and wear a black Aussie hat, and about the only strangers who speak to me are short women at the grocery who need something off the top shelf, lol.
My primary motivation for open carry is that I am compelled to in certain places, by law; otherwise, I carry concealed.
I OC all the time with my wife, who is now 7 months pregnant. I get some odd looks and double takes, but that goes with the territory.
