How about writing a book that outlines how and why religions are wrong and illustrates a viable alternative viewpoint.
Or would that viable alternative viewpoint BE a religion?
The problem is that people WANT to be sheep.
They WANT to be told what to do.
They don't want the responsibility of thinking for themselves.
People crave religion.
Religions (not all, mind you, I am generalizing here) skillfully and purposefully take advantage of that fact and exploit it to force people to succumb to control and even want to be controlled even more.
The key isn't to abolish religions, but to introduce a new one that people will grasp on to.
But one that is positive and forces people to think for themselves.
Kind of weaning them away from the need to be controlled.
Make them realize the benefits of real freedom of thought, personal responsibility and strength of mind.
That's the tricky part.
Give them a religion that ISN'T a religion.
How do we do that?
