I disagree. In True Christian morality, communism is not acceptable/fine.With Christian morality, communism would be fine too ))) Personally, I admit it doesn't matter at all - I've lived under both communism and capitalism.
Without Christian morality any system is doomed. Or at least the canons of Islam (but not radical and not militant) are needed.
As a True Christian, follower of Christ Jesus/God, I cannot do certain things, live in a way opposed to His teachings. I understand there are people who believe differently, in another god, that is a choice according to the knowledge one has. I believe It matters.
