Regarding egalitarian-like arguments, I suspect many express opposition to embryo selection not because it’s a consequence of a positive philosophy that they state and believe and defend, but because they have a negative philosophy that tells them what positions are to be attacked.
I suspect that if you put together the whole list of what they attack, there would be no coherent philosophy that justifies it (or perhaps there would be one, but they would not endorse it).
There is more than zero logic to what is to be attacked and what isn’t, but it has more to do with “Can you successfully smear your opponent as an oppressor, or as one who supports doctrines that enable oppression; and therefore evil or, at best, ignorant if they immediately admit fault and repent; in other words, can you win this rhetorical fight?” than with “Does this argument, or its opposite, follow from common moral premises, data, and logical steps?”.
In this case, it’s like, if you state that humans with blindness or whatever have less moral worth than fully healthy humans, then you are to be attacked; and at least in the minds of these people, selecting embryos of the one kind over the other is close enough that you are also to be attacked.
