I am happy to debate the topic on opinions and principles. Because you and I just don't need guns, you know. All of the problems encountered during the day, they are solved with hammers or keyboards or gadgets or whatever. See? So we don't need guns.
Until, you know. Until we do need them.
I understand your point of view. But with such argument you can justify anything.
