I don’t agree with this at all. Incestuous relationships involve power dynamics that make them abusive far more often than not. Also, even though a single generation of incest doesn’t involve TOO much more risk for genetic defects, multiple generations of incest definitely does. If it becomes legal and socially acceptable, it could happen enough to make that issue come into play.

It’s not social justice to defend people who want to have sex with their own children. Even if those children are now adults, that’s just an abusive dynamic.

That's what happened to Charles II of Spain. From Wikipedia:

Charles was severely disabled, both physically and mentally, described as "short, lame, epileptic, senile and completely bald before 35, always on the verge of death but repeatedly baffling Christendom by continuing to live."[6] He is thought to have suffered from the endocrine disease acromegaly and a combination of rare genetic disorders often transmitted through recessive genes, including combined pituitary hormone deficiency and distal renal tubular acidosis. In his case, the so-called Habsburg lip was so pronounced that he spoke and ate with difficulty his entire life. He did not learn to speak until four, walk until eight, was effectively treated as an infant until he was ten years old and did not attend school.
