I've joined the dark side...w8 I'm already there

Incest is only considered sick because it causes birth defects in the children born from it. Since children can't be born from gay incest, there's really not much wrong with it as long as both people are ok with it.

 

Whether or not you consider it sick, it's important to state that there are very serious implications and consequences from carrying on an incestuous relationship in many parts of the world.

 

Never said I was considering one.

Though if find it interesting new jersey will not prosecute for incest if both individuals are above 18. At least in the world of Wikipedia.
