I think this is the best description about the two sides. Pro choice people only care about the mother, while pro life people care about both the mother and the child. The pro life movement is about doing all we can to help protect all human life.
You are absolutely correct in your assessment. The pro-choice movement not only believes that a prenatal child’s life is meaningless and worthless, they literally dehumanize their own sons and daughters. Of course, they only do this to assuage the guilt and remorse they feel for killing what they know is an innocent living human being.
