... For instance, the musket was once the state of the art military firearm. We could also compare the cross bow, or the long sword... with the musket... with the state of the art service rifle.
You argument is foolish. But no doubt it gets many nods of assurance where you live.
A drone and a nuclear weapon are also state of the art. Me owning either is not a good idea.
And if you can't be trusted with a Nuclear Warhead, you can't be trusted: PERIOD.
And absent trust, you are not suited to live among free people.
As for god-given rights, there is no such thing....
I see... and that explains why you are unworthy of trust.
What you are also incapable of understanding, is that while you are unworthy of trust, because you lack the means to trust others, your disordered mental state, also provides that you've no right to your life and anyone who finds your life to be an inconvenience, is entitled to squelch such, with impunity.
It's quite a paradox, which sadly, falls well beyond you limited intellectual means... but it falls beyond the means of any and all Relativists. Which is why you creatures are a menace to society, on the whole and why you fuck up everything on which you have the slightest influence.
