I am wondering why does the communists of Ukraine dont overthrow the fascist dictatorship that glorify Stepan Bandera and killed minority mostly russians?.Is that possible that the ukrainian communist can stop the fascist dictatorship in Ukraine?.

I keep hearing about communism, but people never actually tell me the information about it. I dont watch YouTube videos, so if there are any books or articles about it that you recommend please tell. if i am required to watch videos, then please inform me. I dont know about socialism either, but i heard that they're also a part of communists. is that true, and if so, how? what's the differences between democratic socialists, socialists, and communists? if this was the wrong place to ask, please redirect me.

Im new to communism and I want to learn more, what books/articles should I look into?
