People’s stupidity seriously never cease to amaze me. Someone on Reddit wrote this during my debate:
“If evolution developed a way for siblings to not want to fuck each other (this is not just expressed in humans but animals too), then this is because it is advantageous trait. Survival of the fittest. There is no moral right or wrong with evolution. Nature selects things because they work well and provide an advantage to future offspring and competitive survival of that genealogy. You can harp on all you want about what is supposedly fair and morally equitable.
But it really doesn’t matter. Nature has already proven that the reproductive method you are advocating for has no merit. It doesn’t matter if you think nature is being fair to your views or not, it is just how it is. Now if you want to go have incest, or old women want to get pregnant, or people with genetic defects want to reproduce, there is nothing stopping you is there? But everyone should stop and consider whether they are being kind to the life they want to bring into the world, or whether the suffering that person will experience would mean they would rather have not been born. There at least is the moral conundrum.
Maybe one day this can be solved by science and genetic screening and modification. If incest was an advantageous evolutionary process, we wouldn’t even be having this conversation as it would simply have been part of our cultures and religions for thousands of years anyway and there would be nothing even slightly taboo about it at all. People wouldn’t even be questioning it.”
This was my answer to them, a too polite one as internally I was just thinking “well fuck you”:
“Not everything is about evolution or nature. Being gay isn’t an “advantageous trait or process” for reproduction either. Neither is being asexual. Nor transgender. All of these were taboo, and now look where we are (at least in the west / first-world countries). Taboo doesn’t mean wrong, immoral or unacceptable. The same thing that happened with the LGBT+ community is going to happen with incest regardless of how ‘unnatural’ it may or may not be.
And I repeat: Most children born from incest are healthy. Many people in incestuous relationships never have children. Some incestuous relationships are gay or transgender and can’t have biological children.
But I do agree with you on something: Maybe one day this can be solved by science and genetic screening and modification. You can definitely bet on it. Science and technology progress at an amazing rate. Someday the stupid excuse that “it causes birth defects!” will simply cease to exist.”
