I don't find this article particularly offensive, just extremely naive.
For all it's problems, in the U.S. we still enjoy both freedom of speech and freedom from the tyranny of socialized govt, both have reared it's ugly head in pretty spectacular ways recently..
Namely, you can end up in jail if you teach your dog to salute at Heil Hitler, or if you decide you want to present the middle finger to your govt overlords on a traffic cam, or if you think you might like to send your child to a different hospital that offers hope, no matter how grim the ultimate outcome, or if you defend yourself in your home from a robber with a knife.. Just to name a few..
The first and second amendments of the U.S. are unlike very few In the world. Statistically most people are very unlikely to encounter such gun crimes like school shootings, but you'd never know that because we have a media and culture driven by ratings and agenda.
But there is a lot of truth that people have much less value for life. That's not just a U.S. problem.. I'm a U.S. citizen, so I can criticize the mayor of London openly without fear, but their plans(or talks) to remove any and all knives from stores and the hands of their citizens is a pretty good example.. But no knife, no problem, you can do it pretty effectively with a truck, I recall 80 or so were killed a few years ago, and at least 10 were killed a few days ago in Toronto. And anyone with any sizeable amount of intellect could probably devise a plan that is highly effective by stealing a semi.. Someone with actual intelligence could probably devise a scheme to drop small IED's via drones and could probably be pretty lethal and remain effectively safe from capture, let alone any of the other mainstream methods..
And on top of it all, even with all the gun bans, one of the worst gun massacres in recent history occurred not in the U.S., but good old Europe.. Many countries have effectively banned all weapons, But that just means that the law abiding citizens are the ones who become defenseless.. I've sarcastically argued numerous times that the Charlie Hebdo attacks were fake news, and the people were just made up, after all, such firearms are actually banned there, so such an event isn't actually possible to happen, those weapons are banned..
It gets even better when looking at countries like Mexico, S. America etc, where the police may actually be part of the mob, flip a coin as to whether you'll survive if you call for help (I suppose if your passport is blue or from the euro block they probably try to take care of you for tourism sake)..
In any case, I think a recent episode of econtalk with Jonah Goldberg http://www.econtalk.org/archives/2018/04/jonah_goldberg.html summed up a lot of truths about the place we are at in our society, especially in the U.S.. It's quite worth a listen.. Because ultimately, though the above is bad, we often forget that gives have historically persecuted people far worse, and though it's 2018 (as if somehow that means something), it's still happening ( IRS/FBI)etc..
Ultimately, These are problems govt cannot solve, and the answer the govt will give might not be an answer that's good, for average Joe at least.. But I do think, in the U.S., It's a road we are heading down..
