Enlightened algorithms? Progressives ask Big Tech to censor 'bad' ideas

The second link gives me an endless captcha.

The closest to an example that I could find in the very verbose third link was the 'okay' hand gesture.

Is that the kind of expressions you want banned? What about, for example, a website that catalogues black-on-white murders, and ignores white-on-black murders, would that be allowed, or is it harmful?

What about the reverse?

The third link also says anti-immigrant speech should be banned. Does that mean "I believe immigration should be reduced" gets censored? If anti-immigrant speech should be banned, does it then follow that anti-non-immigrant speech is also not permissible? E.g. statements disparaging the local majority population?

When you say "harmful" speech, implicitly you mean "harmful to my values". Others see harm in speech that you find agreeable. But you are confident that the enforcers will share your values, and the speech that ends up banned won't be, for example, undermining the territorial integrity of China.
