For instance, they often posit the Holodomor famine and genocide was justified.

I think this is an unfair representation of their views. They think that there was a famine that was exasperated by Kulaks that were mad their farms were being collectivized, and that there was no intent on the USSR side to cause a famine, pointing to aid that was sent to the region or a letter from Stalin(?) being taken aback that the local admin hadn’t been communicating this earlier and demanded that large efforts to alleviate the (impending?) famine go into place immediately
