It’s very easy to ridicule a position by pushing it to the farthest extremes... it’s called the “slippery slope” logical fallacy, Zina.
Human beings have been manipulating animal genetics to meet our needs, desires and vanities pretty much forever: more wool, more white meat, more milk production; flatter faces, excessively sloped hips, colors/patterns.
Manipulating genes for desired/targeted traits has also yielded undesired/unexpected traits. This cannot be negated.
Right, wrong, or indifferent, people have the power to decide the genetic makeup of animals. People who believe the end product is worth the problems have the ability and legal right to propagate and sell that end product. People who believe the problems outweigh the value of the end products have the right to not purchase them or propagate them.
