Interesting to note that during the Obama years the US has dramatically increased it's import to export ratio.
We actually have hard data on this, thanks to the National Instant Criminal Background Check System (http://en.wikipedia.org/wiki/National_Instant_Criminal_Backg...), we're going on something like 30+ months where each month's sales are greater than the same month's a year previously. I can get details, or e.g. check out the NSSF's reporting on this (the real gun manufacturer's association).
The utter ruthlessness of Fast and Furious is also telling.
You're also ignoring what I think is the most fundamental thing: anyone who makes a habit of balancing their checkbook can predict that things are going to get ugly when we can no long have "trillion dollar deficits as far as the eye can see", and that we're clearly going to be on our own as that plays out?
How about HUD's Section 8 policy that among other things moves criminals out of the central cities into formerly peaceful areas, which is now slated for a big expansion?
Another thing, related to the above, a steadily graying population, etc., is that ever more states have shall issue concealed carry regimes. Since Obama was elected Iowa and Wisconsin have joined them, with Illinois (!) in a few months; that'll make 43 out of 50 states, way more than 2/3rds the population.
You're demonstrably wrong about "no one's going to take our guns" when it comes to slave states like New York and California that have confiscated them in recent memory, and in the latter's case is poised to do another round, but in general correct ... because in most of the US we won't tolerate it, one way or another. Keep pushing, though, if you want a second Civil War with the half or so of the nation that's "the fanatical right wing".
