Steven, these criminals dont require to perform their crimes in the "name of Allah", or strictly in compliance "with the Koran", they only require to be brought up in the midst of a culture which views the behaviour of our children as unclean and immoral.

As I stated earlier,even if this assertion was true, it does not give any other culture the right to practice racism against them, or dehumanise them into sex objects to be used.....often not for money, but to family members.

Regarding your last post, the norms referred to I suppose were society's norms. The norms of producing and contributing to an extended family.....normal breeding patterns....the norms which stabilise humanity and produce some sort of order in human existence.
Simply tacking a word like "marriage" on to certain types of human behaviour, does not make it necessarily beneficial to society.
