It doesn’t, ML is based on the philosophy of primarily Lenin (hence the name) and is meant more as the political means of transitioning power from capitalism to the eventual anarcho-communist existence that will be enjoyed by all. In general, they don’t defend the atrocities of ML states and are often the most critical of states like Cuba, Vietnam, the USSR, and China. I’m very skeptical of ML because it necessitates 1 party rule and I see all states as authoritarian, but claiming ML necessitates defending atrocities is a position of ignorance. It’s like supporting the US, it doesn’t mean people also support the genocide of latinos on our border.
