Christians are supposed to fight against ALL evil and communism is the epitome of evil.
You simply read the rhetorical title and by your answer I know you did not read the article, as the author spoke your answer.

Evil will rule and grow until He comes back to set things right - God has declared it and the cesspool will only get deeper and more fetid as time passes.
