Yes, I guess nothing is ever that simple. But the fact that you are able to have a dialogue about this shows that leftist nomenclature can lead to understanding in the same way as any other nomenclature, which is the understanding that's developed in a back and forth dialogue about a subject. Maybe if the OP had declared their belief as an unquestionable religious dogma (as many people do with their political opinions), there would be grounds to criticize them, but they didn't.
