Someone gotta ask him what he thinks of incest, and then ask him how he thinks mankind developed from Adam and Eve only.
It seems there would have had to be a first male and female to gain the sort of self-awareness that we understand. These are the individuals that I think of when I think of Adam and Eve. Even if others gained that sort of consciousness slightly after them, one would expect Adam and Eve, as the first, to be their "teachers," and to be the founders of the culture. Certainly the spiritual mother and father of humankind as we know it.
Anyway, on subject...is this guy trying to use government funding for this? If so, it would be one thing to mention that there are dissenters and critics--but an actual exhibit seems like WAY too far. If someone wants to set THAT up, they can do it on private money and the free market will decide what it thinks of that. Obviously I would not take my money or my kids there, if I had kids.
