As I said to Pygoscellis, I regard that as simply none of your or anyone elses business if you are meaning to imply it towards me and my own offspring. PERIOD.
He is the master of the house. She is his offspring, his biological property. Therefore that is his private prerogative if he so wishes. Personally I am not into incest, but if I DID happen to be into it, it would be NONE of anyones business whatsoever. And if they wanted to ever MAKE it their business then they would receive by me something that I will refrain from giving description to all the ghastly details of what I would do to them. Answer me this: Do you think the Taliban would be ones to bow down to your state authority if they were being threatened to have their offspring seized from them because of some apparent mistreatment of their offspring? I bet you they wouldn't! They too would fight you to the death.
Prove it then. You obviously are unaware that some sects and schools of Islam support my position and that there is an exemption when it comes to offspring! I would have never converted to Islam in the first place if I ever thought that that proviso was not included. Private property rights and the attached absolute parental authority are utterly sacred to me and I would never give that up for anything in the world.
Because as far as I'm concerned my offspring have no inherent connection to you or to your society. I put a very heavy emphasis on clan, I am not a collectivist or a monogenist. So another part of my fundamental reason for this is that I object to different species of hominid laying judgement on what I do in my private affairs and how I raise my own biological offspring. I don't regard a different species of hominid to have the inherent right to judge how I conduct my private affairs. They have no more right to judge me than I have any right to judge a rhinosaurus which I deem to be mistreating its own offspring.
I don't care if you wish to speak that on behalf of your own offspring. Just don't speak on behalf of MINE. That is a no go zone for you, sorry. *I* will be the one to decide such matters, not you.
