You know you’ve gone too far when…

When a liberal semi-icon starts quoting the conservative side’s talking points.

The Left had better sober up and join an intelligible good faith debate about US immigration policy and the enforcement of existing laws or this will lead to exactly what Brent Tarrant laid out and what Mr. Trump maladroitly hinted at. Instead, of course, we will more likely commence another bootless campaign over guns. Here are some plain facts about that. There are already enough firearms of every sort loose in this land to commence hot civil warfare and they will not be surrendered by their owners. The horses are out of the barn on that one, even if sales of military-style weapons are outlawed. Any effort to confiscate them from people already possessing them will only provoke more overt antagonism between the two poles of American politics — and would probably lead to exactly the sort of violence that sober observers discern on the horizon.

Everyone sees it coming and no one seems willing or able to do anything to stop it. It’s starting to feel like a cross between 1835-ish through 1860 and 1914. We know how those worked out.
