Timothy Martinez6 said:This opens up a whole mess of questions. Here are a few that are currently stuck in my head:
1) Is the mere possibility of something happening—like developmental issues in a child—enough justification to ban incest and the ability to marry? Should the "right to marriage" be tied to the potential for offspring, or should it be treated as entirely independent of those biological concerns?
2) Following that logic, should we ban marriages between men and women who aren't related by blood if genetic testing shows a high risk of their children having developmental disabilities? Isn't that kind of thing already prohibited in California?
3) What about relatives who are sterile and can't have children? Should they be allowed to marry since there's zero risk of any developmental complications from offspring? And what about incestuous relationships between people of the same sex (like a father and son, or grandmother and grandson)? They can't conceive together either...
Look, setting aside my own weak logic in that last bit of the first point—where I was basically trying to pivot toward how people might twist it against gay marriage—I was just pointing out the main reason incest is banned in most places. It's not always about the act itself. The real kicker is that repeated incestuous relationships spike the inbreeding coefficient, making the long-term genetic fallout way bigger than it looks on the surface.
If you step outside the whole "kids" conversation, there isn't anything inherently wrong with incest. Most people aren't attracted to close relatives not because of shared DNA, but simply because they grew up in such close quarters.
Case in point 1: A brother and sister get separated at birth, grow up totally unaware of each other, meet later, fall in love, and then find out they're siblings. Sick? Yeah. Tough.
Case in point 2: A boy and girl who aren't related grow up in the same house. They see each other like siblings and stay completely asexual toward one another their whole lives; honestly, the mere thought is repulsive to them.
So, there's no double standard
per se. But the foundation for making a decision is totally different, and it should be.
