Was Ayn Rand Right? Did She Predict Our Dystopian Future?

It is fashionable these days to celebrate progressive values and woke politics. I have avoided politics my entire life. I always had enough intellectual combat to satisfy any such urges in my law practice. However, opposing viewpoints and challenging rhetoric seem to be under attack these days, and it cuts both ways. At its root, such behavior can develop into a mass psychosis, in which outsiders, with opposing viewpoints to the current "wisdom", are shunned and attacked. We used to live in an idea combative society, in which opposing ideas were the subject of reasoned discussion, debate, and sometimes the debate came with raised voices; but, never, or almost never, with violence. What happens when the marketplace of ideas becomes a one size fits all, one product only, dispensary? Can society survive, over the long term, in a place where the only residents produce nothing but argument and violence?
