Not the person you asked, but you and everyone reading your comment know that’s not a good faith argument.
The reason incest is frowned upon and often illegal is because of the danger it poses to any potential offspring. Many genetic diseases rely on recessive traits that require both parents to carry the recessive trait in order for it to be exposed. If two biological siblings have a child, that child would therefore have a massive amount of recessive traits exposed since both parents would share a massive amount of DNA
At a population scale, genetic diversity is critical to survival of a population, and a collapse of genetic diversity through too much inbreeding tends to lead to a very unhealthy population that can be easily wiped out through disease. This is much less of a risk with random incest today thanks to how much humans move around these days, but the flip side is that there is some risk of this from so called “super surrogates” who have genetically fathered hundreds or thousands of kids. The likelyhood of these kids meeting and reproducing can be quite high, which can therefore noticably reduce genetic diversity in a population, and ultimately reduce the health of a population






Just to muddy the waters, I worked with a guy who had “system administrator level XII” in his email signature and one of the teammates asked him about it. His response was that he just put that in to see if anyone noticed and occasionally bumps the number up when he feels like it’s about time to do so.
So you never know when someone stuck a private joke into their email signature like that. Heck when I was brought back to my role I was never given a clear job title so I just put the most accurate job title I could think of in my signature of “IT Contractor”
