So you ARE taking the position that a couple who can't have children shouldn't marry?
nope...taking the position againts gay marriage.
am just explaining what the effects could be over time.
Marriage has a meaning. The union of one man and one woman in a lifetime, monogamous relationship. If gays want a similar kind of relationship, that may be fine, but it cannot be called marriage, as that dilutes the meaning of the word. You could call a tricycle a car, but a car is a four wheeled, motorized vehicle. If you call a tricycle a car, you have diluted the meaning of the word "car."
Then there is the "where does it end" argument. If 2 gays can marry, why not 3? 4? 100? How about a brother and sister marrying? a whole family could be "married"? What logically would stop it? Just my unvarnished thoughts.
