Usually I like to avoid the "left-right" paradigm all together if I can help it. Its just not particularly useful in most instances. If you say "right wing" or "left lean" that says basically nothing to me, unless explicitly in a toxic atmosphere with people arbitrarily dividing an other from amongst themselves. I've used "left wing propaganda" to describe the world view of propogandists before I think. I pretty much reserve leftist hesitantly in generalized reference to people with personal problems, spiteful partisan hacks, party and personal problems over country. Normally I would associate "leftist" with state worship or kissing up to authoritarians and another term "right winger" as a pejorative reactionary often connotating paranoia, as they are commonly used in my experience.
