I'm speaking, or referring, to a more... abstract understanding. An idea whose time has come is unstoppable.
Now, when you're talking about tyranny, or tyrannical entities, taking things by force, then, yeah, I guess having guns helps. I'm not totally sure how much it helps, but I'd rather the people have them than NOT have them, if put to it. Keep in mind, I am all for gun ownership... 100%. I don't blame guns for any tragedy, anymore than I blame physics for Hiroshima! But, we should be able to acknowledge the tragedies and problems and discuss solutions.
And, as has already been discussed, the idea that American citizens (or any citizens) resisting tyranny by using guns is archaic. Solving anything by use of destruction, or threat of violence, is archaic. I realize that humans love them some archaic shit, however. We're not that far removed from our primate ancestors, I guess. America isn't anywhere close to armed insurrection. If people can stream Hulu and have a Papa John's (or whatever comfort food) nearby, they're good to go.
