According to CNN today, the couple shown in the photograph are brother and sister, and have had four apparently normal children (read the full story on CNN). The brother has done jail time for the relationship and some of the children have been taken by the State. The couple, despite much hostility, are trying to have such relationships, which have been thought of as taboo for centuries, legalised as they are already in some European Nations.
What do you think about this issue? If gays eventually get legal rights to marry, why not siblings? Why shouldn't mothers be allowed to marry their sons or daughters?
Should a line be drawn in the societal sand or does anything go these days?
UPDATE: It seems that two of the four children have disabilities according to the latest news I've seen. That surely makes the situation clear: let siblings have relationships if that's what they want but kids are a no-no!
