Quote - The only censorship that is explicitly disallowed by the US Constitution is censorship of opinion by the US Government, and all state and local governments who adhere to it. This is why public property is uncensored,

As the country is controlled by companies, shareholders, churches and media that own almost all, all private institutions, they can imposse censorship at its own will.
All you hear and know comes from the media, that are private, the goverment owns nothing and so, no problem to apply censorship to anything you hear, watch or know.

Lenin's paradise and you live happy in this paradise.

PS. During Feudal times there were kings, but there were landlords too (private property) and were the landlords that dictated the rules and not the king!
Nothing changed, poor Washington, Jefferson......

Stupidity also evolves!
