I used to carry but it was in its holster by my side and for use on the enemy should he come calling and outside these United States of America.
I never carried at home in these United States and perhaps my reasons were selfish. I did not ever want to be the subject of a law suit and just about every use of a gun that leaves a living corpse ends in a lawsuit.
People I know carry and I have no problems with that. What I figured to do was to avoid going to those places that made carry a practical and necessary form of dress. I just don't go to any place that I think will feature armed killers. This is somewhat harder to do now that schools, colleges and theaters are such places.
I am also, now, 29 years older than I ever thought I would be. I have, by and large, done what I came to do and if the exit is shown via a gun wielded by an enemy, that's not really anything new for me. I so don't want to lose my mind and slip into dementia and senility. I watch in quiet despair as the smartest man I ever knew slips away moment by moment. He was the smartest man I ever knew and taught quantum physics at West Point in a gap year after getting his Masters Degree and building a nuclear reactor in a swimming pool as a break from fighting the war in Vietnam.
OTGH, I almost always carry a locking blade knife whenever I leave the house. As the reader can see, closing in for a kill in a terminal attack is still an option. Short of a shot to the head, I figure I can reach or die trying.
