It’s the same reason that we have laws against incest.
I’d argue it’s also the fact that because of the low genetic diversity of the parents children born from incest have a higher chance of developing genetical diseases.
The chance is lower than most people presume but at the same time: why gamble?
What about same sex incest, or where one or both partners are sterile, or between adopted siblings who aren’t related genetically? That would still be considered wrong, right? Even though there wouldn’t be genetic consequences
Personally? IDGF about what two consenting adults do in bed. My only objection is when it comes to children being born from incest because of the higher risk of genetic diseases.

Don’t know where you from but AFAIK that’s perfectly legal in Germany.

But that’s still not a 100% consistent argument and it leans into another morally complex topic: eugenics.
Because, if you argue that way, you’d have to clarify your stance towards people with genetic diseases/disabilities in general.
And if you follow the logic, we would also have to shun/abolish sexual relations between people with genetic disease or who carry the respective alleles, so that their offspring have a higher chance of inheriting a disease (in some cases way higher than with random siblings).
It might be the root cause, why there seem to be marriage rules in most human societies, that exclude intermarrying of siblings (especially considering that the risks increase drastically if you keep procreating that way for generations), but the current taboo is not entirely rational and seems more based on cultural tradition than current understanding.
Again, personally: As I have one confirmed genetically transmitted condition and one suspected genetically transmitted condition this is a dilemma close to my heart and TBF I haven’t reached a final conclusion for myself yet. On one hand I think it is unethical to conceive a child knowing full well, that they have a considerable higher risk of disease, and yet I don’t think GATTACA was meant as an instruction manual. As so often in life the answer is somewhere in the middle.

Those laws and customs predates knowledge of genetics significantly.

Yes but that is also a rationalization after the fact. First, it was ew, then we figured out that there were also rational reasons against it.
It’s been the norm in many countries for centuries, so can’t have been seen as EW as you claim
That’s a great justification for the EW
