It is only possible for a society to find good, better, to grow with all humanity, if people have full access to new ideas, different ways of seeing things and the world.
If there is freedom to break the consensus, to displease the majority, to disagree to the limit.
If someone sets a limit, even if it is as well-intentioned as possible, that limit becomes a taboo.
And probably the very problem that this taboo tried to hide ends up getting worse, by creating tensions and divisions, and destroying everything in its path.
What good is a being with wings, if its feet are attached to the ground?
For freedom, for the possibility of the emergence of new ideas, or even for the recycling of good old ideas, there is a price to pay: that of accepting that a small portion of stupid people use that same freedom to say horrible things, to offend and displeasing others.
At that time, society must know how to curb its impulses of control. There is no perfect world.
If a person is censored or punished for something she has spoken or written, even under the most seemingly innocent and just of arguments, this power of censoring can - and will, it always does! - be used to silence good and do evil.
Think about it.
