> I stated my policy preference elsewhere on the thread: give up on national firearms policy, back down on the maximalist Heller interpretation that says MSRs are off the table for state regulation, and allow states to license (on a presumption of must-issue basis) all semi-automatic long guns if that's what their citizens decide they want to do.

From the perspective of many, that's "allow guns to be banned". It'd be sort of like saying "back down from the maximalist Roe v. Wade position" or "back down from the maximalist Brown v. Board of Education position", and then getting mad when people accuse you of being anti-abortion or pro-segregation.
