"Why are parents and their children forbidden to marry one another? Cut to the chase and the answer is simple. The right to marry includes legal recognition (legitimization) of the married couple’s right to have sexual relations with one another. But it is wrong for parents to have sexual relations with their children. It’s wrong for siblings to have sexual relations with each other. It’s wrong for adults to have sexual relations with underage children. Obviously, unless Mrs. Bush means to argue that these restrictions are unjustified, a committed loving relationship is not enough to establish that people “ought to have” the right to marry."
http://www.rightwingwatch.org/content/right-wing-leftovers-280Let's try to follow Keyes for a second, shall we?
2 adults who love each other and are gay -> Marriage -> Will lead to parents marrying their own children because they love each other (What?)
Do I have to smoke something before I can understand what Keyes is saying? Is that how it works?
