Whats right about it? In most cases of incest there are victems involved. Usaully a trusted family member violates another, We here about a lot of "mature" cases of incest where grown up brother sister or father and grown up daughter engage in it....etc. But this is seldom the rule. Now if this was the case then I can not fault that--as adults. But when it comes to the innocent, it is unacceptable.

Now many would fault incest as a biological evil...but looking at history (ancient Egypt as an example) the odds of a biological disaster are surprisingly few; otherwise for those royle houses of ancient Egypt would have been very brief which was not the case. One must remember you and I are but 1/4 mom and dad and 1/8 grandma and grandpa (1/8 for each grandma and 1/8 for each grandpa) and therefore there is still room for genetic variations
