You're right, they technically don't. But they ban everything that can be even remotely interpreted as "offensive". To give you one example, I got banned for pointing out the appeal to nature fallacy. I've said that rape and murder is technically natural and yet it's not socially acceptable. Literally just that. Nothing less, nothing more. But someone either misinterpreted that simple sentence or found it offensive because of the context of the conversation, and thus I got banned.
But either way, defund the police is not mainstream anywhere - that’s pretty universally understood to be a fringe (and ridiculous) proposition, and has already proven its devastating consequences.
Again, goes to show the polarization of the US.
[1] Obviously, black lives do matter and fascism is bad, but as slogans "Black Lives Matter" and "Anti-Fascism" represent very radical political programs. You should be as suspicious of these slogans as I assume you are of slogans like "All Lives Matter" and "Anti-Communism".
Everyone has a personal Overton Window - the set of ideas that they think are reasonable and acceptable, even if they personally don't agree. When most of the personal Overton Windows approximately align on a particular topic, then we have society's Overton Window.
For example, think about gay marriage. 50 years ago, maybe even 20, 95% of society thought that gay marriage was clearly not acceptable. That meant that 95% of society agreed with 95% of society's personal Overton Windows on the topic, and so we had a clear society-wide Overton Window.
Now we have maybe 30% of people who still think that gay marriage is clearly not acceptable. We also have 40% who think that gay marriage is clearly in bounds. Of those, maybe half (so 20% of the population) think any doubts about gay marriage are clearly unacceptable. There is no position which a large majority of society finds acceptable. (All numbers made up, but I think they're in the approximate neighborhood.)
The society-wide Overton Window didn't move. It shattered.
"Socially acceptable" is, necessarily, relative to some defined group.
Especially in a political system with limited major parties and partisan primary elections (especially if they are closed, but even if they are open in theory but tend to attract a specific mostly-stable community in practice), and a substantial population that participates in neither parties primaries, considering the Overton Window within each party and/or ideological identity group as well as the "national" Overton Window can be useful. The GP comment could be rephrased without, I think, change of meaning as "the Overton Window of the community of the ideological Right and/or the Republican Party has moved relative to the rest of society such that it excludes much of the window as viewed by those not ideologically tied strongly to the Left or Right faction".
I see no evidence that that is the case.
And the question you have to ask is how do you see it when it happens to right-leaning people? Is it happening in your immediate neighborhood? Or is this supposed social "cancelling" happening to people who have pre-existing or readily-made-available access to strong, highly-visible, wealthy network that shares their story as outrage fuel and/or enables the socially "cancelled" a highly-visible platform to do so?
Information gathered as unstructured anecdotes, especially absent analysis of the systematic biases in how the information gets to you, is not a reliable basis for drawing conclusions about relative frequency, especially when the topic is specifically differential suppression of viewpoints and information.
And I suppose that's probably a good thing.

Agreed that the article is about government censorship, and I commented before I read the article.
However, given that the US government at least has shown very little backbone in its threats to regulate social media companies, their tendency toward more censorship also seems concerning.

This kind of political speech has no place in a democratic society. The fact that it comes down to social media and Internet providers to regulate it, however, is reflective of a policy failure. Keeping calls for extremist violence out of the public sphere ought to be the responsibility of the criminal legal system, not private business.
A "liberal" on Facebook calling for the beheading of a conservative politican would be banned (possibly even arrested) immediately. The opposite can and does happen every day, with no penalty.
