By the time the opportunity arises to actually do anything about it, a whole load of "conservatives" will be furiously denying that they ever were. In some cases to tribunals and commissions.
Nobody should give the slightest respect or deference to those ideals if invoked by anyone who supported the Republican party after "very fine people on both sides". There is nothing "conservative" about 99% of people who claim the label, and there's nothing moral about their position.
They can either organise with the gun fetishists or take the opportunity to separate from them. But there's no reason to suggest that conservatism in its true form has anything to do with looney gun fetishists who pose with guns in Christmas cards.
All of this can be done without changing the fundamental right to bear or own guns.
