Eugenics literally means "well-bred" so any attempts to re-encode ourselves has a direct involvement of Eugenics, so I am not performing analogy here but invoking the principle of a fortiori. Particularly I am not claiming ethics of gene-editing or Eugenics in general, but that the public has no appetite for this as seen with the strong ethical claims against Eugenics.
By a "non-binding eugenics guideline" I mean something akin to "ex-convicts should not produce" or something, I mean there is absolutely zero state or national guideline that I know of that invokes arguments of eugenics, if you know of one then I am mistaken.
