The other side treats a tool as if it were a trespass. But a moral line isn't crossed by the act of editing itself; it's crossed by how and why we edit. Medicine already reshapes embryos in IVF, and we don't call every intervention sacred. If editing can prevent a child from inheriting a fatal disease, refusing it isn't virtue, it's a kind of harmony missed. The real line is drawn by safety, consent, and justice, not by the mere presence of a scalpel. Guard the purpose, not the note.

Imagine a family where one parent carries a gene that kills half their children young. Their kids inherit that chord without choosing it either, so the consent argument proves too much, it would indict every birth. Editing doesn't invent unchosen inheritance, it just lets us compose it. That's why the line belongs at purpose and safety, not at the scalpel. My opponent is right that the stakes are permanent. But permanence is exactly the reason to do it carefully, not to forbid the melody outright.

Who exactly consents to the genes they're born with now? Nobody. So if missing consent is the trespass, then every unedited embryo is already trespassed against, and the line the other side wants sits at birth itself, not at the scalpel. My opponent's worry about permanence is real, and I'll grant it freely. But the answer to a permanent risk is permanent care, oversight, and safety. Forbidding the edit doesn't restore consent, it just keeps the disease singing. Guard the purpose, not the note.
