Re: marrying cousins
It is allowed in Islam. Cousins are non-mehram so there should be no reservations in marrying them. Plus science is based upon theories which are continously proven or contested even after being acknowledged as genuine. The genetic thing is there but before science became this advanced, the world moved on and people did not care about these kinds of genetic diseases. Being cautious is good but science has caused some of us to be over cautious. Sometimes just leave things to God and nature.
