Sure, every gun is dangerous. But put a musket next to a machine gun and you see there are many levels of dangerous. Some are made for combat and should be left in the hands of trained soldiers. Others for licensed citizens and law enforcement. Others for average citizens for self defense, sport and hunting
Come on Slade.... The musket in 1770 was the "super dangerous" weapon of choice at the time.
Times change, so does the item in question.
Hell's bells, just 100 years ago people were still getting around mainly by horse, horse and buggy (or other animal drawn cart)or steam locomotive.
I get it, you keep wanting to appeal to emotions and cannot see a "valid reason" for anyone to own what you deem acceptable. Problem is, I can.
You deal with your little slice of the world and I bet rarely ever venture out of it. I deal mainly in a rural setting and there are many and various animals to be wary of.. Least of them the 2 legged variety. I also have to deal with the business world in a city enviroment. I don't encounter every type of incident and I hope I never do. I just don't want the law abiding to be limited should they ever have a need. I have been blessed in my personal life as to not have a need... Yet. However, my previous life/upbringing/career/life experience leave me with an understanding. Just because I don't believe it to be so doesn't mean it isn't needed for someone else.
What you want doesn't negate what someone else needs.
