I say this as an Australian. We have a far more restrictive system of gun control than the US and yet we still see tens of gun deaths a year, because some gun deaths are okay even if we set the number a lot lower than the US does.
In a broader sense, it is of course not okay to shoot someone, but that's taking the quote out of the context of gun control measures.
instead his opinion is more, "all gun deaths are ok"
he was never going to be worried about the count or a more nuanced comparison of how many gun deaths are acceptable
I disagree with him on guns, but that is the point.
And I have the sensation that all the ones we drive a car nowadays are engaging in a similar type of risk acceptance, we know there's too many people dead every year in car accidents, but we still believe that overall having access to cars outweighs the risks, without meaning that car accidents are acceptable and trying to improve the safety of the cars and roads meanwhile.
Kirk thought in a similar way that gun control and possession were definitely good for the US population and that gun deaths were still a price to pay for it.
BTW, gun possession is also legal in all EU countries. It just not considered a right, but a privilege. And this is accepted by most parties in EU, both left and right.
