Doing nothing changes nothing. Positive action moves the earth. It all starts with one person taking action.
No. This is an illusion. Or delusion. Or both. As far as I observed history and actual occurences positive activism is/was
always assimilated.
Take Jesus (first man known by me who critized the something like the fiat system) and christian belief. Assimilated.
Take the 68 movement in his radical strive for freedom. Assimilated.
The ideals and the actions of the US-american revolution from 1776. Assimilated.
The human act that really moves things on earth is a better understanding of (rules of) reality.
Take firearms. The knowledge about how to manufacture working firearms is spread. It is not imaginable that warfare reverts to stones, swords or bows.
Take cryptography. The knowledge ist spread. It is not imaginable that someone starts to encrypt in the way from 500 years ago, where letters where moved around.
