Talk politics.

The state forbids forms of incest (though many laws go further than is required by science, there is no evidence that cousin marriage* is dangerous, but serious problems can arise from sibling and parent marriage* )'

*it's old fashioned but in law marriage acts as a stand-in for having kids with a person.


I see your point, though.


I object morally to someone who screens out "gayness" (if this is possible) yet, I don't know what sort of law I would write to stop then.
