I mostly agree as well.
To be clear, open carry people generally do not scare me. As a rule, people who are commit a crime will not be advertising it. But I know oper carriers do make a lot of people uncomfortable.
I also think they are setting themselves up for trouble. It's but a matter of time until someone either tests them or runs their mouth to start some crap, and the odds are too high that things will escalate.
Lastly, an open carrier has given up their element of surprise. The who point of being armed is so you can defend yourself and loved ones in the event of a dangerous situation, and if you're open carrying and you're in a place where stuff is about to go down, you're the first one the bad guys will target and or take out.
I'm a supporter of carrying, but concealed is smarter.
