Can you specify any compromise offered to us by the gun grabbers in, say, the last 50 years, that wasn't of the form "we'll only take half of your arm off"?

Maybe the Firearms Owners Protection Act of '86, which had a poison pill ending sales of new machine guns to civilians? Nowadays lots of gun owners who weren't watching the BATF exterminate gun culture in the '70s and early-mid '80s say we shouldn't have accepted that deal for the precedent it established, which was furthered in "assault weapons" bans (prior to that there were no firearms technically banned from civilian ownership, even if NFA arms like machine guns had onerous acquisition regimes ... which the BATF is even now trying to make more onerous/impossible).

Stepping back a bit, after, oh, 81 years of bad faith (going back to the NFA of '34 which attempted a de facto ban on handgun transfers for all but the rich), might we be somewhat justified in not being willing to give up another fraction of an inch? Especially when we have members of our community like my father who remember how things used to be, without problems? (OK, he was 4 years old when it passed, but you get the idea, e.g. when he was in high school in mid-late '40s he and others would store their guns in their school lockers while attending to make hunting before or after more convenient, and "school shooting" were unheard of.)
