Toddy we need to get this in perspective before this becomes an issue. Yes this topic started about something else, but hey that's life. It's evident that you are not a fan of firearms- fine and good for you, but a lot of us here are. Firearms are not dangerous (at all!) It's the people that leave them lying around in an unsafe conditions, near to/loaded with ammunition and of course the inappropriate use of them by criminals and some unfortunate people with mental health problems.
I have been fortunate enough to carry a firearm in a police role overseas for 3 years. I drew my weapon once (someone threatened to set a dog on me) and never fired it, yet I get immense fun, yes fun, out of target shooting and also rough game shooting (The things I consider edible I eat).
It is not appropriate to impose peoples views upon other without recourse / redress. By all means tell someone you don't agree with their thought process(es) but the other sub forum you mention is no more appropriate to address this (diversified) topic any more than this sub form.
Firearms are safe- people aren't.
