And the basic idea of politics is to displace and replace all war. Yes?

I'm not aware of that? How about " War is the continuation of politics by other means " ? Clausewitz. Or - " Better Jaw, Jaw, Jaw than War War War " - Churchill

For centuries the words ' democrat ' and ' democracy ' were political swear-words.

Why do you mention one political party and not the other? Its a generalization?  You could read it the same way with ' Republic ' and ' Republican ' if you want.

Now its the turn of  ' anarchy ' and ' anarchist '.

Heads up.  That's centuries old. No. Anarchism starts less than two centuries ago. 1840's - 1940's - 2040's. Come back around 2044.

If you can't stand the heat then get off the cryptoanarchist internet.

This makes no sense. Okay - " If you can't stand the heat then get out of the cypherpunk kitchen ".
