What law?
Try Section 230 is part of the 1996 Communications Decency Act. Go ahead, actually read it instead of ignorantly spouting off about it.
Once a provider censors in any way by deciding the content allowed, they become a publisher, not a provider. Go ahead, read the law instead of mouthing off about it.
Except, they don't.
"No provider or user of an interactive computer service shall be treated as the publisher or speaker of any information provided by another information content provider."
Section 230 also says:
"No provider or user of an interactive computer service shall be held liable on account of—(A)any action voluntarily taken in good faith to restrict access to or availability of material that the provider or user considers to be obscene, lewd, lascivious, filthy, excessively violent, harassing, or otherwise objectionable, whether or not such material is constitutionally protected; or
(B)any action taken to enable or make available to information content providers or others the technical means to restrict access to material described in paragraph (1)."
So show me the text of 230 that supports your position.
