There's a difference in not believing in it and not allowing someone else to do it. When you say "infinity", or comes across that you don't think anybody should ever have a gun of any kind. I personally don't believe in smoking, but I recognize others do and I support their right and ability to do so responsibly.
I do support everybody's rights to do it whatever they want as long as it's in accordance with each country's Laws. Apologies if it came across otherwise.
For me though, with how I've been brought up, and where I am in the world, I personally don't see the need in introducing a child to guns.
In another place, another time, that would probably change though.
