Anarchism

Yes, it's either the terminally online, or the people that have managed to actually make it far enough that it even matters. In the west, it absolutely doesn't matter, except perhaps in revolutionary strategy, ie Anarcho-Syndicalism vs Vanguardism vs etc.

Day to day, the same exact praxis persists: educate yourself, improve your life and understanding, advocate for positive change, unionize, build up your community, and educate others. It doesn't matter what leftist tendency you personally prefer, the praxis on a day to day level is the same.
