Update below

So yesterday I went to see Inside Out 2 in Fishers. Going into the theater I saw a guy flash his gun and then hide it under his shirt, so I told the theater manager about it.

The guy was in my theater, and had a bunch of kids with him. During the previews a lady came to talk to him and he left the theater for a bit. When he came back he had his shirt tucked behind his gun and an arrogant swagger to his walk.

I know this is Indiana and you can open carry now without a license. I personally am terrified of guns and find this whole thing appalling... But I know that's my personal problem. But to bring your gun into a movie theater packed with kids who are there to see a children's movie to me just seems evil on a whole different level.

Can anyone please explain this to me in a way that makes sense beyond the ignorant "they can't take our guns" excuse?

Update: I genuinely did not expect this post to take off like it did. I guess I should have. I was appalled at seeing someone so blatantly carry a gun into a kids movie. I described this as evil because I personally don't think kids should be exposed to stuff like this. In hindsight I may not have been any better than those parents who say exposing children to lgbtq topics is evil. I do apologize for that.

Some points of clarification: As for the term "flashing" his gun, he had it out in his hand showing it off to other members of his group in the parking lot before going in. I think the general consensus from commentators is that this is poor taste at best and makes him or his family a target for bad actors at worst.

I told management about the gun because if I were the manager of a theater I would not want guns carried into my theater. I let them know about the situation and let them handle it how they saw fit.

No, I did not think for a second a guy bringing a bunch of kids to a movie was going to shoot up the theater. If I thought otherwise why would I go on and watch the movie? But people can be irresponsible and misinterpret situations. If someone well meaning with a gun misinterprets a situation, people end up dead. If for some reason a bad actor started to shoot up a theater I don't think for a second that the average "good guy with a gun" could accurately identify and take out the threat, especially with the light of the projector blinding him. If anything he would probably escalate this hypothetical situation and get even more people killed, especially if the bad actor used gas as was done in the frequently cited Aurora situation.

As for me personally, when I said I am scared of guns I mean people with guns, not the things themselves. Especially people who have guns just to have them and who don't know how to responsibly own and operate one. I have taken tun safety courses in the past when there was a gun in my house and I know the basics of handling a gun. Personally I will never own or carry one for many reasons, some of which I have explained in responses below.

Yes, open carry and concealed carry both make me incredibly uncomfortable but I know that is my personal problem, especially living in a red state, and I don't try to force my way of thinking on anyone else. But if I see someone behaving in a manner that is threatening or bringing a gun into a place where they are not allowed I believe it is my moral and social obligation to at the very least report it, which is what I did.
