Doubling down on what? Do you know what "doubling down" actually means?

The comment I replied to was talking about humanity as a species. I responded by narrowing the discussion to individual countries because mental health care varies dramatically from one country to another. Some countries have excellent mental health systems; others don't. The United States, in my view, has a particularly poor one.

The fact that the original incident occurred in Argentina is irrelevant to the point I was making.

More importantly, I can only speak from my own experience. I've lived in the United States for the overwhelming majority of my life, so that's the system I know. Why would I pretend to speak authoritatively about countries I've never lived in?
