No liberal is a part of the radical left. Not Classical. Not modern.

Libertarian used to be synonymous with Anarcho-Communist but today, in the English speaking world, it means Ron Paul and the free market. If you mean the former, yes, that is part of the radical left. The latter, no. It is definitely not. Libertarian Socialists are a part of the radical left though. Right wing libertarians are not.

I'm not sure what you're talking about here. Anarchism is a part of the radical left is that's what you mean.

When I say "radical left", I mean Socialism as a whole. This includes market socialists, Anarchists, Marxists, Utopian Socialists, Christian Socialists, and anyone else who believes in some variation of "social", i.e., worker, control of the means of production.

The essays I would recommend are

• The Principles of Communism by Friedrich Engles

• Why Socialism? by Albert Einstein

• Are We Good Enough? by Peter Kropotkin

He's an Anarcho-Capitalist (not to be confused with Anarchist) and in the videos I've watched he came across as rather obnoxious and a bit bigoted. if he continues in the direction he's going, I wouldn't be surprised if he abandons Anarcho-Capitalism and embraces Dark Enlightenment.
