We feel the right is long established. THEY DON'T. Or rather they feel our right to arms is limited to only those arms that THEY approve of.
And that's the bottom line, until/unless some GOVT agency that THEY respect announces we do have the right, they won't listen. (and even then, I doubt they will stop trying to ban guns)
They see GUNS as the problem. We see people shooting each other for fun and profit as the problem.
The only time these gun ban advocates have shut up, slowed, or toned down their rhetoric was for a short time after 9/11.
A small number of them even admitted that they had been wrong to focus on privately owned firearms as the greatest danger we face. With a couple thousand people dead, many thousands injured, and two of the world's tallest buildings (or was the Twin Towers one building??) destroyed, without a single gun being used, the evidence was pretty obvious.
Only took them about a decade to forget that, and a few more years to resume their full court press....
