Outside of the fevered imaginations of gun rights advocates, I've not heard credible reports of any secret, unspoken agenda to confiscate all guns by any legislators. It astonishes that the slightest scintilla of a potential for complete confiscation (which probably 95-99% of Americans DON'T want) is sufficient to induce essent.ially an unreasoning, CT-level, impenetrable firewall of obstinance against common sense change.
Well, some have a different opinion. It was asserted earlier that Feinstein was specifically referring to "assault weapons" when she made her statement of intent in 1994. Not everyone agrees.
Here's some others whose intent seems pretty clear.
