I don't think that the state should tell people who they can or can't marry, so I obviously wouldn't support any prohibition on cousin marriage anymore than I would support any prohibition on same-sex marriage.
This.
The reason why laws like this exist in the first place is because of moralistic paternalistic WASP Eugenics prudes who desperately wanted to limit the kind of "folk" who could reproduce. But of course, knowing how much many on this forum loves such "freedom fighters", I don't expect many to understand the consequences of having a state dictate sexual mores because "West Virginia" or other reasons.
Of course, this is the part where somebody opens up the pro-rape accusations to which I counter you must be pretty desperate if you are using a rape argument to counter why sex should not be allowed at all between consensual actors.
And I'm saying this as somebody who is not at all attracted to any of his cousins.
