Oh look, a Liberal is about to ban dissent from a progressive. Fuckin suprise suprise my guy!
I'm a socialist, fuckwit.
As stated in the other correct attribution of causes is not denial or apologia. Did I deny the 1 million dead on the gulag system?
Admitting a million people died in the GULAG as a denial of the accusation that the USSR committed atrocities is not exactly compelling.
Did I deny the famines?
You're saying they were all caused by one little guy, just a little silly fellow with an idea, instead of admitting the systemic issues involved. So yes, that's denialism.
…and on your point. The linked page and others elsewhere confirm Lysenko’s ideas were on the rise before 1938, and were involved in the 1930s causes of Holodomor.
The linked wiki page clearly outlines Lysenko's career, and nothing about it suggests that his work became ultra-popular ten years early, when his career was still in its infancy, and caused the fucking Holodomor.
