The firearm is just a tool, it becomes part of your daily routine. You pick it up and holster it like you put your wallet in your pocket and your watch on your wrist.
I check to make sure it's loaded, but other than that there's nothing special or exciting about tucking the holster in my belt. No "OMG A GUN" feeling, no excitement, my heart rate doesn't jump. It's just normal to be armed and you sort of forget about the heavy lump of metal and plastic secured to your belt.
That being said, I've never forgotten about it enough to pack into a prohibited place like a police station or a bar, and CERTAINLY NOT A FUCKING AIRPORT.
Also, we shouldn't be giving TSA a pass here, assuming the congress critter actually went through security like us normal folks.
I gave other examples of "tools" like a watch or a wallet. Tools are just a means of getting things done, and aren't in of themselves good or evil. Some tools are more dangerous than others, just like some jobs are more dangerous than others.
Trained and responsible adults do dangerous jobs, often with dangerous tools, in public, all the time. Similarly millions of law abiding Americans legally carry pistols every day, and you'd be surprised how little crime they commit with their tools compared to the overall public.
But that's probably not what this crowd wants to hear, and that's ok. I'm just chiming in to lend a perspective that might not be the status quo in places like this.
