I’ve had a similar experience. I have actually engaged with the tankies in good faith on several occasions, and it has just gotten those account banned for I guess being a leftist heretic? For arguing that there is more to socialism than Marxist orthodoxy? For opposing campists? Idk, they really seem to dislike that, and these days It’s pretty obvious that the worst sin on ml is making tankies look dumb by actually knowing even basic political science.
