In the mid 1800s the USA still had slavery. And the rest of the civilized world shook their heads. In this regard the USA, an amazing and vibrant and innovative country that I admire with every bone in my body, was an embarrassment.
Defenders of slavery put forward all kinds of specious arguments in favor of their barbaric dehumanizing exploitation: including the fact that slaves are mentioned in the Constitution.
Now the USA is shackled with another anachronistic relic: liberal gun laws that put extremely destructive weapons in the hands of crazy people. And the rest of the civilized world are shaking their heads and tut tutting with all right.
Defenders of guns are putting forward flawed arguments based on things like the second amendment (which doesn't apply to a modern social context or to modern semi-automatic weapons) and defending yourself from the "gubment" and "dem d@mn revenuers" (yeah, good luck fighting the government
).
The self-defence argument and "only criminals will have guns" are also flawed. Liberal gun laws are like a destructive spiral. The surroundings become more dangerous, so decent folk feel they need guns to counter it, which makes more and more powerful guns available, which makes the environment more dangerous. And so on.
