Communism had just as much contempt for Judaism as a religious faith as for Christianity. The twenties were an era of tremendous pogroms with tremendous fighting. Ukrainians died one way and Jews another. But you will see only one victim as good and the other as evil. Life is much more complicated than anything you would ever be able to imagine in your wormish head.
Freedom means taking responsibility for one's actions.
Many Ukrainians have not learned the lessons of freedom. But I know that no amount of suffering gives one the right to harm others. But I have fundamental problem with people like you who reflexively rally behind those who perpetrated such crimes and feel an inherent obligation to see them as some form of just revenge. And find endless excuses for them. That is your crime.
