Today, the government has tanks and drones, which might not end in your favorite when you're showing up with a 9mm.
Why can't those people stand to the fact that they want guns, because they think guns are cool? From my point of view, that is the only reason.

That's a good calculation to your point and I understand your way of argumentation. I understand that black market is a horrendous problem in countries with many guns around and that black market prices in the US are a joke compared to e.g. Europe or Australia.
But it's leading away from my point.
I am pretty sure that there is no need for anyone to own guns, looking at the lifes of everybody I know, people survive greatly without them. I am more in doubt about the reasons that gun owners are repetitively putting out there, when questioned why they want a gun. Protection against burglars is highly questionable, because the responsible gun owner will need to open a safe, load the gun, face the burglar and shoot somebody who came to take his TV, all of which has to happen in the middle of the night, most likely. Protection aginst tyranny or "the government" was possibly a good idea, when both citizens and government had the same weapons.

That is the question I was talking about. I mean, ok, when you desire to own a gun and act responsibly, lock it in a safe etc. Fine. But I think almost military grade weapons is taking it to a level that's frightening.

An assault rifle is a selective-fire rifle that uses an intermediate cartridge and a detachable magazine. The U.S. Army defines assault rifles as "short, compact, selective-fire weapons that fire a cartridge intermediate in power between submachine gun and rifle cartridges".
That's what Wiki says. Isn't AR the abbreviation for Assault Rifle?
But anyway, I'm not here to define words, I am questionning the purpose of said rifles in private homes.

While the rich try to avoid their responsibly to their environment and neighbourhood by evading and avoiding taxes, excluding themselves from solidarity and the rest of the world in gated communities.
I will not start to emphasize on a possible perspective, as I currently see none that politically could be transported to the people (as many of them still believe to be rich someday). But I have to admit that the currently dominant Anglo-American capitalism is not developing in a sustainable direction, it even looks like the end of it may come in our lifetimes.

But you have to admit that the system by far has developed to be an almost financial feudalism. The rich have grown super rich and the number of poor people rose exorbitant.
The truth is, that wealth in all cases means the opposite to many others. The device I'm writing on, my clothes, my furniture and many more are being made by extremely poor people, if not children, in order for me to buy it for a decent price.

Yeah, philosophy!

Now will you leave them at least some diversity here :)
