Just because something is legal dose not make it right, sleeping with your friends 16 year old son would be legal but not right , holocaust denial is legal but not right.
In my work I had come across a family were the parents were related and mum and both sets of grand
Arenas were related also the mum and dad split and dad re married another relative they have 7 children altogether and only one can talk 2 have mental Heath issues and the most disabled cannot see, hear and has a mental age of a 3 month old the boy is 24 the one who is the least disabled is 16 she was married last year to a cousin she has not right hand and her toes are mal formed
Like i said net to superstar if you don't know why its wrong to sleep with someone you are related to then you need help
The fact that someone can bring themselves to sleep with someone they have been raised with says a lot about the person and also those who haven't been raised it's about not acting on your feeling just because you feel a certain way one might meet their sisters oh for the first time and fall madly in love but yu don't act on it
Their are only a few cultures in the uk that practice this and they usually have other tabbo practices also
