"most gun owners are buying fashion items"--thank you, I've never seen it better said.

As for where the line is drawn, well, I think the biggest reason people don't want to draw any such lines is because the US government isn't a tyranny and isn't heading there in any way.

One of the biggest political issues in recent times is, of course, health care, but can you imagine how stupid it would come off as to try and lead a revolution against mandatory health insurance? Likewise for every other hot-button issue--armed revolution because now gay marriage is a thing? Because it's harder to find incandescent light bulbs? Mandated gas mileage improvements?

Wherever you'd draw the line and not have it be 100% asinine, it'd be so far from reality that even declaring "here and no further" would make you look dumb.
