Daniel: I don't agree with you that religion is man-made. If you would take out the time to find out how the Qur'an was revealed, it will change this view of yours. Just for your information, the Qur'an was revealed to Prophet Mohammad (PBUH) who was totally an illiterate person. How could a person who could not read or write put up such a book. Surely, there was a great power that made this happen, and that is Allah.
Yes, I do agree with you that religion has been used in the past and continues to be used today as an effective tool for people to come into power and rule over others.
As for Germany following the "one man, one wife" policy, suggest you advise your government to bring in amendments to your constitution in this respect. It will help the country greatly in controlling fornication, unless you people want to live that way and enjoy the best of life by keeping one legal wife as a showpiece, and several secret ones for enjoyment.
And this will d-e-f-i-n-i-t-e-l-y give a child the benefit of knowing who his or her REAL father is.
