Note that they were banned for doxxing, not for intolerance or hatred.<p>Generally I strongly favor free speech and believe the answer to 'bad' speech is more speech. However, there always are limits such as slander, harmful deception (yelling 'fire' in a crowd), provocation to crime ('assault the man in the front row!'), and more. I think there may be a way to clearly and justly draw a line for white supremacist and other hate speech, if and when we want to do it.<p><i>Tolerate all but intolerance itself.</i><p>There is some theoretical support:<p>* Think of tolerance as a social contract: I tolerate you if you tolerate me; or, everyone tolerates you if you tolerate everyone. If you break that contract then you have no claim on everyone else's toleration.<p>* Karl Popper's Paradox of Tolerance. <i>Unlimited tolerance must lead to the disappearance of tolerance. If we extend unlimited tolerance even to those who are intolerant, if we are not prepared to defend a tolerant society against the onslaught of the intolerant, then the tolerant will be destroyed, and tolerance with them.</i>[0]<p>On the other hand, the always incredible Stanford Encyclopedia of Philosophy makes some good arguments against it, especially that humanity will abuse this new authority.[1] Partly for that reason and partly to err on the side of individual liberty, I would apply this rule only when there is a practical necessity. One requirement would be that the intolerant group poses a threat. For example, a group of intolerant Jainists in Los Angeles isn't a threat - they are too few to threaten anyone in that environment. In a tiny town where they are the majority, or in a locked room with one Confucian about whom they are saying intolerant things, it would be a threat.<p>But this all is my personal analysis; I'd be interested in some established standards such as workplace law, neo-Nazi speech in Germany, etc.<p>----<p>[0] I can't find an authoritative source or discussion, but Wikipedia covers it: <a href="https://en.wikipedia.org/wiki/Paradox_of_tolerance" rel="nofollow">https://en.wikipedia.org/wiki/Paradox_of_tolerance</a><p>[1] <a href="https://plato.stanford.edu/entries/toleration/" rel="nofollow">https://plato.stanford.edu/entries/toleration/</a> - Search the page for "paradox of drawing the limits"
