Agreed on the homophobia of Stalin*. About Beria and Katyń i agree with Furr, but the mere fact we are not outright dismiss Beria as literal demon from hell or consider Goebbels as sole authority on nazi crimes is already a step beyond liberal consensus which is accepted as premise even in communist spaces. The fight against anticommunist lies is not a single effort, and i will say it's the worthy effort. We should never, ever, give them a finger with no resistance.
*I don't exactly remember Furr stance on it though
