It is the freedom to doubt the reality of what has been regarded as Good, then to doubt the possibility of Good, then to subvert/ invert/ destroy/ (I mean reform) the Good in the name of the Better.
(There is nothing actually Good - not God, nor marriage, nor the family - but somehow there always is something Better than them.)
Unconstrained freedom to attack the Good is now regarded as the most important of all Human Rights.
Yet since the Good is Reality - this means that the ultimate modern freedom, defended with the full force of the modern state and mass media, is the Right to deny Reality.
A short term for the denial of reality is Psychoticism.
Thus modern freedom is a freedom to be psychotic; and an unconditional right to have this delusional state defended by all necessary means.
