However, you create a path for the next person to use the same argument to censor other speech. Maybe they'll be riots over the next war involving the US and it'll be for "the good of society, to prevent violence" and it'll get censored as well.
Anyway, we've had this sort of thing in America, but we've probably largely forgotten the history (Lady Chatterly's Lover, Fanny Hill, and so on) and haven't really paid attention to the small-scale occurrences that are still ongoing (e.g. public school libraries are often pressured to remove "controversial" books).
Yes, there are concerns about concentrated, oligopolistic markets, but those are solved by breaking up the major players -- not by legislating some requirement of fair service for literal swastika-waving, Roman-saluting Nazis.
People are not entitled to claim freedom of speech for posting Nazi trash on their own private website, and then claim freedom of speech from other private entities refusing to do business with them. Everyone has a negative right to express Nazi views. Nobody has a positive entitlement to demand material resources from private actors to express Nazi views.
The disgusting thing here is that, for many years, if we on the Left pushed for a universal basic income, or for single-payer health-care, we would have the difference between positive and negative freedoms kindly explained to us by the political center and Right. Now a bunch of (again) literal Nazis have a sad, and that we have to quietly listen to the center and Right tell us there's no more distinction, that Nazis have a positive entitlement to be Nazis? It's completely disingenuous!
Or should the Communist Party file a lawsuit to demand a stipend from tech companies for spreading communism?
Communist Control Act, 50 U.S. Code ยง 841
>The Congress finds and declares that the Communist Party of the United States, although purportedly a political party, is in fact an instrumentality of a conspiracy to overthrow the Government of the United States. It constitutes an authoritarian dictatorship within a republic, demanding for itself the rights and privileges accorded to political parties, but denying to all others the liberties guaranteed by the Constitution.
If we stand for the "right" of Nazis to compel private actors to do business with them (and holy shit does that violate the typical libertarian-capitalist positions of the American Right!), why don't we stand for the actual right of Communists, revolutionary socialists, democratic socialists, and anarchists to operate openly at all?
AFAICT, while the near total lack of government enforcement (and lack of appeals in the few relevant cases that have gone to court) have prevented many or high-level court decisions on the overall constitutionality of the Communist Control Act, the only federal court to rule on that issue ruled it unconstitutional, and the only Supreme Court decision relating to the Act held that the Act did not prevent the Communist Party from participating in the New York State unemployment scheme.
So, it's not clear to me that the Communist Control Act has any substantive legal force, and it's pretty clear that whatever it seems to say on its face, the force it does have is not actually outlawing the Communist Party.
Please don't let that happen in America. Making up hate or blasphemy reasons is very easy.
