Communism IS fundamentally bad. Why? Because it’s inherently authoritarian, oppressive, and violent. The utopia is just that, a fantasy. We’ll never achieve an a perfect society. Therefore, this ideology will always be permanently stuck in it’s authoritarian, oppressive, and violent stage. The authoritarians in power will never voluntarily give up their power, they’ll never stop oppressing and killing people, and they will never agree that the utopia arrived. The communist utopia will always be just around the corner.
