This is what makes Hacker News such an astounding resource for thought provoking insight. I take the American perspective on free speech as nearly a theological imperative despite the problematic side effects. The alternatives strike me as far worse. Free speech drives faster resolution and remediation to the socially unacceptable. The ideas and behaviors highlighted by the reviewer are not new to society and collectively we do not stand in a place in a place, "never before seen." Our tools for communicating, identifying, and correcting the evils in this world are better than ever. Evil is just so damned ingenious. That isn't speech's fault.
