"Anarchists, unite!"

To people not understanding anarchists, yep. Mind you a whole load of faux anarchists don't know the meaning of "without authority"

I'm not sure the anarchists of yesterday would identity with some people calling themselves anarchist today.

Nope, when the world is totalitarian right now, unite... there will be a push back by anarchists.

They start their meetings with a cry of "Disorder please ladies and gentlemen".

Nah, just that that the terms anarchism and stateless are imperfect and don't communicate the actual goals very well.
