Isn’t it interesting how the new vapidity so resembles the old vapidity? Train people to second guess everything that they already know, and they can be readily controlled by a strongman, a state, or a cult. In any event, they can be passivated into a form of personal disregard and self-destructive behavior.
If relativism signifies contempt for fixed categories and those who claim to be the bearers of objective immortal truth, then there is nothing more relativistic than Fascist attitudes and activity. From the fact that all ideologies are of equal value, we Fascists conclude that we have the right to create our own ideology and to enforce it with all the energy of which we are capable.
- from "Diuturna", 1921, by Benito Mussolini
So you can see that Relativism, as we react negatively to it, has so many political uses. Especially if you can make dilute the importance of questioning ideas, authority, or can make the act less relevant. As you know, there are people still trying to struggle to find nothing important, or comparatively important, or objectively worse than anything else. For example they kill in the interest of convenience and call it a ‘choice’, by removing the relevance of the act of actively ending a life. They relate the life into a clump of cells, and relate the act of ending it into a health procedure.
You see, it’s easy when it’s all relative.
