Weeeeelllllllll. I never realized there was much of a "radical left" until Lemmy. I'm a SOLID progressive. I would consider myself a social Democrat. If you are the same then a Marxist Leninist leftist would consider you an enemy. They don't think their policies could ever be truly enacted through gradual change and that a violent revolution is essentially required.
I'm not a centrist, but ML leftists scare the shit out of me. Meeting them on Lemmy is when I discovered that I'm not actually a "leftist" and it made me do quite a bit of soul searching on what these political terms actually mean.
