Antitheism

[Mister Agenda]

That doesn't make any sense. Do you take issue with the brainwashing, or with the ideology being forced upon other people?

If you take issue with the brainwashing, then you might want to have a problem with everything society makes you do by way of law as well, for starters. Because that's textbook brainwashing as well.

If you take issue with the ideology being forced, you're an antitheist.

Indoctrination is a better word, but this method stems from theism itself. Without the overarching authority figure no one would feel the need to accept what is being handed down uncritically.

Accepting what is handed down uncritically is what children are evolved to do.
