Everything comes in shades of grey, and that's a particularly dark one. That doesn't mean small concessions aren't the right thing from time to time. In the same way while Americans are allowed to bear arms they aren't allowed to bear nuclear arms. I doubt you'll find a single person in favor of unrestricted domestic nuclear proliferation in the name of the second amendment.

Especially when the country isn't even sure about bump stocks.

How about we address such things on a case by case basis?
