Freedom of speech is often banded around, i think this is a misnomer, that is perpetuated by politicians, lobbyists and radical fringe groups, who have a skewed view to promote . As humans irrelevant of religion, we should all be following the basic shared thoughts, no killing, stealing, lying, adultery, decency, consideration and equality to all.
Once you take onboard these principles, you discover that you have developed an internal
set of principles. Each persons would be different versions , so we developed rules and laws to abide by. These we accept are not always perfect for everyone, but OK for the majority. As a result we already accept a degree of censorship.
So freedom is an ideological impossibility .
