I do think labels are helpful for coming to a coherent understanding. Rejection of labels and focusing only on details can lead us to not notice how these details intersect and interconnect, leading to counterposed beliefs simultaneously held. Some people will reject the convo outright based on label, but these people likely aren’t going to be swayed anyways, and are looking for an excuse to end the convo. That’s why I just openly state that I’m a Marxist-Leninist, it helps explain my views in a more concrete way than needing each bit to be teased out over the course of a convo.

IRL though I tend to not bring up that I’m an ML unless I am at a protest or event or otherwise trust the person deeply.
