When Human Life Begins Is Not a Matter of Belief

President Joe Biden made an irrational statement the other day about when human life begins, saying at a press conference: "I respect those who believe life begins at the moment of conception. I don't agree, but I respect that. I'm not going to impose that on people." Except this is not a question of "belief," but one of biological fact. It's a question about which science -- rather than politics or ideology -- has long known the answer. Indeed, embryology text books are clear on that point.
