The paradox isn't "you don't have to tolerate intolerant people because they're bad and tolerance is our goal", the paradox is that tolerating people who then proceed to seize power and outlaw all disagreement with them undermines tolerance.
Unless there's a credible threat, it's a misuse of the quote.
If you're talking about anti-Nazi laws in Germany, fine, but I see the quote trotted out all the time to justify eg twitter banning some alt-right-adjacent nerd for having bad opinions.
Nobody paid much attention to what that guy on gab was saying to like-minded folk on gab... Until he grabbed a gun and massacred everyone in a religious building.
When the threat evaluation models aren't trusted, the spread on evaluation of "credible threat" increases.
The paradox of tolerance would be if we decided to be tolerant of a pro-mosque-shooting political party and they took power and instituted mandatory mosque shootings every Friday. We would have messed up in that case.
It's not, "I demand people who disagree with me on less clear-cut issues be silenced because they're bigots, according to me".
Well, that's the issue, isn't it? Do we all agree? I think a lot of people do. There's a disturbingly large number who do not. And there are corners of the Internet perfectly willing to entertain their fantasies of establishing such a political party.
I think whether one should cut that off at the knees by monitoring such sites and, when necessary, squelching the channel or one waits until someone has grabbed a gun to act on the ideation is an intensity slider on paradox of tolerance that reasonable people can disagree on.
Given the sliding scale, it's probably a case-by-case issue. Hard to come up with a general principle that's going to universally apply; give an example of something people have been silenced on that they should have been allowed to continue, and there's debate to be had, but on the general principle, both sides can probably agree that there's times to silence and times to not.
Or glam metal albums that glorify satanism?
We've been through this before.
> Would you also support banning hip hop albums that talk about shooting cops or other violent crime?
If we're talking no-platforming, I don't think the question is whether society bans it; I think the question is "Would you compel Wal-Mart to sell hip hop albums that talk about shooting cops or other violent crime?" And I would not. But it's a sliding scale which is, as you've noted, tied to the likelihood of the group in question seizing enough power to concretize their ideas. In the US at least, hip-hop artists aren't an organized political structure intent on overthrowing the US government.
White supremacists are another story entirely. It's pretty unambiguous what "blood and soil" or "Jews will not replace us" mean. And a lot of Americans are deeply concerned with the risk that that ideology has its tentacles extremely deeply embedded in one of the two primary parties at the federal level in the US.
The conclusion was that parental advisory stickers are cool and will help sell your album, and I'm glad we got there as a society.
Incidentally, Wal-mart in particular was on the conservative side of that culture war episode, and they did in fact refuse to sell those albums while also selling entire racks of guns.
Mind you, I'm not saying that we should tolerate such folks, either; and once you get past their tiresome, narcissistic self-aggrandizement, it's not like they have anything worthwhile to say. But that's a different argument than Popper's; it assumes the existence of some minimally basic ethic of thriving, and says that no, you can't aim to destroy the world around you even if you would be quite OK with everyone else doing it back to you in return.
Indeed they did. And the US government did not compel them to sell the albums, nor should they have. The albums found their audience in spite of some channels deciding it wasn't a kind of speech they would tolerate on their premises.
Similarly, some of the speakers who have been no-platformed will find their audience without a university's help; that doesn't imply the universities should be compelled to help them. And some toxic moderators and editors will continue to be toxic on some other site; that doesn't imply that site must be Wikipedia.
But I was mostly just nitpicking improper usage of the paradox of tolerance. Righteous censorship of 'bad' ideas might feel good but it's probably not a great instinct to have in the long term -- this cultural moment will pass, the meta-ideas about when it's ok to censor are longer-lasting.
Wal-Mart carries plenty of stuff, though. If you're going to move towards that kind of regulation for free information services, there has to be some other basis for it.
There are plenty of other places to go if Wal-Mart doesn't sell a CD. Not so much in Twitter or Wikipedia's case. Some alt-right 'competitor' with 30 users isn't really a substitute.
Your phone carrier is a service provider that is constrained by the FCC. Twitter is one of many broadcast sites one could go via a phone carrier. But the US, to my knowledge, has never recognized anything approximating a right to broadcast. Not even freedom of the press implies freedom to spew signal over the airwaves, for instance (because the radio spectrum is finite and shared).
Freedom of the press has never implied freedom to use someone else's press, and telecommunications hardware providers aren't in the same category. If your phone carrier cuts you off, nobody on the Internet can read your signal; if Twitter cuts you off, they've merely taken their megaphone out of your hands.
We don't have jurisprudence saying so for websites, because this is new, but it could be argued that a number of websites have reached a sort of monopoly status. Facebook is probably closest, but Twitter and Wikipedia both occupy unique places in society to the point where it's not, just, "go start your own website".
As far as business freedom, remember the gay wedding cake guy? Where were all these "you're not entitled to Twitter's megaphone" people then? On the exact opposite side of the principle, mostly.
I think people having different attitudes regarding the three categories of service is reasonable.
