The shouting came before the self identifying.
Saying tankie is tongue-in-cheek, or simply to upset the people that scream it constantly. I’m a marxist-leninist, formerly an anarchist. I would still be an anarchist if climate change weren’t putting a time limit on the need to get something done too. I decided that I could not sit by knowing hundreds of millions of people were going to die in 30 years (closer now tbh but it was a few years ago that I moved to a leninist toolkit now) while also knowing that anarchism was not equipped to generate the needed revolutions required to save any of those lives. Marxism-leninism and dem-cent parties on the other hand have a proven track record of creating revolution within that kind of timeframe.
I will probably return to anarchism when such timelimits are not in effect. It’s just not morally justifiable for me to sit around using a toolkit that’s not equipped for the time limit when we know what we know.
