Obviously enough, while Evil propagandises for death and against Life, it also propagandises to convince the Good that it must not propagandise for Life.
If we fall for it, we are subjected to its influence.
We're nobody's fools; not any more.
The mission of Life is Life at best; there is nothing wrong in propagandising it.
Rather, it could be said that propaganda consists of convincing of a lie, therefore helping to recognize the truth of things is not propaganda.
Therefore, it's a matter of eradicating the propaganda for death from what we support and of supporting Life, and the degree we succeed is the alignment to the mission of Life.
A map of this path is the evolution of the definition of ethics in history up to that reported here in ethical fundamentals.
