Thanks for your message.
I was tempted to say "Solipsism. Look It Up."
But then I thought such a caption would come across as condescending, particularly to people like you who already know its meaning.
Solipsism is a Big Deal.
The fact that's solipsism is barely on America's radar is a classic case of not being able to grapple with a problem because we can't even name it.
The history of solipsism (as a psycho-philosophical-academic "category") traces back to the ancient Greek, Gorgias of Leontini.
Gorgias details with startling accuracy what is now taking place in America's fake-news-alternative-facts matrix. https://en.wikipedia.org/wiki/Solipsism#History
