Brothers, sisters, parents, kids? No.
First cousins? No.
Second and third cousins? Fine. The science says third cousins share less than 1% DNA. Same risk as strangers.
Age 55+? Generally safe, but the real rule is confirmed menopause. No period for 12 months = no pregnancy risk = no birth defects.
Accidental pregnancies and birth defects are why I draw the line at close relatives. If that risk is gone, I don’t care.
Kids involved? Hard no. Consenting adults? Do what you want. Bedroom, car, train station.....I couldn’t care less.
I’m not the government, but they’re in our bedrooms anyway. Funny enough, some states already agree with me, they only ban cousin marriage if you’re young or fertile. If you’re old or can’t have kids? You’re good.
Am I endorsing this? No. Would I do it? Hell no. But if it’s safe and consensual, who am I to stop them? Let people live.
