This is obviously true. Science explains human nature, and it supports the Catholic Church’s assertion that a new human life begins at conception.
No reasonable sane human being can deny this.
Obviously there are no reasonable sane humans beings in the democrat party or among radical feminazis.
True but irrelevant. The issue is not when human life begins, it is when human life should be given the protection of law as a person. That is irreduceably a political question. Science can hopefully provide insight, but it simply cannot answer the question. It's just not a scientific issue.
