I did not read the article about Kushner, but I don't need to. Censorship shouldn't be done, period (except by parents as mentioned above). The moment you begin down that path is the moment that the process becomes flawed and prone to bias.
Whether or not there are objective truths is irrelevant.
Firstly a world without some kind of censorship would not function. If I put a sign outside your work that you are a pedophile, that would cause you a problem even if it were not objectively true.
If I released government secrets, that would be okay because a confidentiality agreement is a form of censorship (not unlike a EULA or TOS).
Finally, even a conversation about censorship has bias. You have devoted more words defending Alex Jones censorship than you have to the NFL football players who kneeled for the national anthem.
