Epic fail

Playing devils advocate (maybe literally) the idea that Incest is an abomination of sorts surely only old cultural hang ups or religious dogma?

I am not saying that it is healthy or right, but I do not think it is society/goverment's place to criminalise such behaviour and even censor information about it.

That to me, seems exactly the same as criminalising homosexuality.

If you believe Levi-Strauss (he makes a convincing case) the incest taboo is a very rare cultural universal - the thing that changes is what counts as incest. See The Elementary Structures of Kinship for a lengthy, dull expansion of this point
