Lysenkoism got its legs almost purely on branding and ridiculing vast swaths of individuals...BIOLOGISTS.
It later became official Soviet scientific dogma, much to the delight of American farmers, who profited on selling grain to the Soviets for many years as they stubbornly continued to ridicule, then later FIRE, any biologist who disagreed with the Lysenko view.
It starts SOMEWHERE, and it ends somewhere, and it works in both directions.
