I've learned a few things regarding this topic, from experience. When you wear Pink camo pants, and shiny black jack [jump] boots to golden corral, in a state in the bible belt, people are going to notice your pistol before your ballsy wearing of pink.
Doesn't matter what you wear, and it doesn't matter how you act. The only thing that matters is if you play into the anti's stereotypes, or you adhere to a semi-professional Open Carry attitude.
I've had days when I've been in a foul mood, and OC'd and still had good and bad encounters with people asking questions, or insinuating some diluted idea of mass murders. I've even had a citizen like me, defend me to a clerk at a gas station, when I told an anti to go "Eat s*** and die".
And when I say semi-professional attitude, I mean like, don't be adjusting your sidearm every couple of minutes, don't put one hand on your hip above your pistol, if you want to put hands on your hips use both hands so it seems normal, dont be fidgeting, act as though its not ever there. And hey, you can even get away with using the handle as an arm rest for those long lines at a check-out xD
