Romantic relationships with cousins, creepy?

[devonin]

Screw anyone that doesn't approve of the way you live your life. It's yours. If they don't like it, that's thier problem!

So you'd be okay with me, if I had AIDS, deciding I wanted to live my life by walking around with open sores, bleeding wounds, and spit at people?

The main objection to incestuous relationships being presented here is medical not moral. People are positing that there are above-average health risks to related individuals having children...this causes problems for the child, not the parents, and it is a justifyable objection to say "Since this increases the risk to the child, they ought not to be able to have a child"

The taboo is a societal safety valve because it's easier for a culture to just train people to think that sexual relationships with family members is inappropriate than it is to train them all to understand the scientific reason why procreation within bloodlines is hazerdous.
