A gun is substantially more dangerous than a jar of bees. Dangerous things warrant suspicion. If you don't see that, I question your abilities in the realm of risk analysis.

It also serves an actual purpose.
If you are just suspicious of anything "dangerous" without appropriate context then I question your peace of mind.
I was raised around law-abiding gun owners and have never felt unsafe in the presence of a firearm under normal circumstances provided the wielder is not intoxicated or otherwise exhibiting alarming behavior. It sounds like you just aren't used to guns.
