I think we have different standards for the start of an ideology. I'm looking for it's broad use as a self identification. I freely admit it has it's roots in the 1800's, and I admitted above the word was in some use all the way back through the 1400's with similar meaning. Although it was mostly used against the church until the 1700s. It certainly isn't just one among many. That was the problem the writers were trying to solve in the early 1900's when they started identifying as Libertarian Communist/Socialist. They were unifying anarchism, council communism, workerism, and a few others. So the idea wasn't to be one among many but to bring those ideas into a tent. That's what was different about the 1890's and the 1910's. It went from a word getting thrown around to a specific ideological label.

I didn't really mean you when I talked about people claiming moral superiority. I was just venting that people are trying to claim it was a coherent ideology contemporary to the very beginning of communism by twisting things around. I also don't care that you took a day to respond, that just means you put real thought into a conversation that should have some real thought.
