I think this is a very poor understanding of the opposition argument.
As an avid gun-owner that’s totally all-for increased gun-control measures, I’m not trying to make murder “physically impossible”. I’m just trying to make it a little harder to perform on a whim.
The homicide rate in the US was roughly 5 per 100k residents a few years ago. For the Brits and Aussies it was closer to 1.
Again, I don’t know anyone in the pro-gun-control camp that is promoting a solution as complete and utopian. As such, it would be nice if critics of those proposed solutions stopped acting as though they were being touted as such. Frankly, it’s a bit dishonest, even if unintentional.
