Well, he does go on to say that he deplores it and it's bad. Denying that human genetics theoretically could change would be such a step that it could embolden those people in a "look at the libs denying obvious facts" type way.

But wait, I'm not saying we should actually kill all babies. I'm just stating a fact.

No one here is denying the fact that genetics can change, they are questioning his interpretation/application of the phrase "work", and anyone who thinks this equates to"look at the libs denying facts" is willfully misinterpreting things, and is unlikely to actually change their opinion

(note I'm not saying you are thinking that - just that modifying your behavior to try and limit that interpretation will never lead anywhere because the people who hold that view fundamentally don't want to change it)
