I would love a sensible conversation with a gun control advocate. But given the appeals to emotions, manufactured truths, and outright lies I don't foresee that happening any time soon sadly.
I've had a few with foreigners.
In the end most of the reasonable ones think machine guns should be allowed but that everyone should just have a gun license and then be able to buy what ever they want without further background checks or anything, along with a competency demonstration for the license.
Demonstrating that it would violate the civil rights of Americans just like an internet ID card would, does eventually force them to concede there is no reasonable argument against guns when it is a right.
