I think that what you are trying to say is that Utopianism is evil, and I can agree with that. Trying to remake man into something else is inherently evil because we are creatures of God and no man can remake us into something better. Freedom, the freedom to follow one's own conscience is a central part of Christianity which all the ideologies you mention try to destroy as well as most Utopian ideologies of any sort. Because they are contrary to the central theme of Christianity, they are evil, but Christianity is not because it does not want to destroy man's freedom to follow his own conscience, it wants man to follow his conscience.

There are or have been Christian utopias, some fairly successful. Some played a significant role in building America, at least in spirit.
