It objectively is calling for censorship, irrespective of whether one considers it justified censorship

The idea that a private platform choosing not to amplify something they don't agree with, something that is clearly spelled out as their right in the first amendment, is "censorship" is absurd. If the local newspaper chooses not to run the classified ad you sent them, that's not censorship. If a big newspaper chooses not to publish the letter to the editor you sent them, that's not censorship. If FEDEX chooses not to ship the package you bring in, that's not censorship.

A business choosing not to do business with you, even in very specific and obtuse ways is not censorship. A private entity has no legal, ethical, or moral obligation to signal boost or publish anything they do not want to.

It clearly is censorship. Maybe you're conflating censorship with the First Amendment? The Constitution only protects certain kinds of speech. Only that of citizens with respect to government, and only Americans. When people speak about censorship, they are referring to all kinds of censorship by people all over the world, including private companies censoring individuals.

So just to be clear: you consider it censorship when the rest of the world tells you "you cannot harass x group by utilizing this set of harmful language"?

It clearly is, what else would one call that? Perhaps it's censorship you agree with and others agree with and maybe I agree with some of it, but it's never the less censorship. It's also censorship when the government redacts documents, but we have granted the government some carve-outs in order to protect national security and other things, which over time has become abused just like your proposition would be abused.

Also, language is not harmful. It may be abusive or offensive but it's not harmful. That's not to say people don't allow themselves to become affected by language --but one can be negatively affected by lots of language that isn't "hateful" but may be truthful or carry unwanted information.

No, censorship would be nobody being able to discuss these topics period on those platforms. That is fundamentally not happening. We've simply entered an era where you need to do it respectfully, which isn't that hard.

Furthermore, language is demonstrably harmful by way of the weight we've given it over the years. We've also made strides in society in recognizing how to avoid using or enabling it in ways that harm marginalized groups.

This isn't rocket science.
