TITLE: My buddy is dating his cousin and keeps asking me if I'm supportive of them, what am I supposed to say!?
POST: So my friend of many years met a first cousin of his for the first time about 6 months ago.  They have been seeing each other for a while now and it seems like things are starting to get pretty serious (to quote Kip).  He keeps asking me pretty aggressively if I think there's anything wrong with that and I always tap dance my way into giving a half answer. 

 Recently he kept it up and I cracked and admitted that I thought it was strange but it wasn't like I wouldn't attend their wedding or anything.  He seemed a little hurt and switched subjects.

Does anyone else think this is strange?  He says he has told a few of his social circle and lots of people have no problem with it.  I just keep thinking of ME dating MY cousin and how extraordinarily weird that would be!  I know it's much more common world-wide than it is in the states, but I don't know how to tell him that his new cousin/girlfriend gives me the jibblies.  

The real tragedy of this is that he has never watch Arrested Development, and has no idea why I keep asking him how "Le Cousins Dangereux" is going.
TL;DR: 
My good buddy is dating his first cousin, and I feel strange about it.  He keeps asking me my opinion.  How does the hive mind feel about cousin love?
