| It was only practised in Egypt amongst the royals, to keep their blood royal. Egypt fell apart because it's leaders were too busy killing each other to notice Rome spreading it's wings. Also, Roman emporers often practised incest, and the imperial rule last about 350 years. The royals of Europe have been marrying cousins for 100's of years and they're still in power (well yes they're heads of state now technically).
The point of legalising incest isn't because it is or isn't disgusting, it's because it's no-ones right to interfere in the bedroom as long as everyone is consenting (and mature enough to consent). I think cheese is disgusting, how people can eat milk left to go off for X many weeks is beyond me, but I don't feel that's a good enough reason to ban it.
As for the kids, well that is crap. It'd be selfish for anyone to try and have a kid with a relative, esp a close one, knowing the risk that runs. However, if it's aloving relationship theres nothing to stop them adopting, we do need more willing parents to look after orphans after all. |
