Um . . . .
Okay, I'm speechless. I can't even hope to use logic here, because there is none to begin with.
I'm sorry you can't follow my argument, but really, claiming you don't understand it is not the same as saying there's no logic to it. I repeatedly explained myself, despite the fact that some people do not wish to understand: if it is in the hand of the legistlature to determine what marriage is, then it may accept gay marriage and not polygamy. If, however, it is a constitutional right to marry, then if it applies to gay marriage it must apply to polygamy (or incest) as well.
And why, exactly, are you comparing gay marriage to "marrying two bricks, a dog, and a Chevy", again?
For the same reason I compared gay marriage to incest in other threads. The point is not that they are morally and practically the same, but that CERTAIN ARGUMENTS of the pro-gay-marriage folks would apply to them as well.
The point, naturally, is to show the weakness of the ARGUMENT that are used to support the recognition of gay marriage, not to claim gay marriage is the same as these other arrangements in all, or for that matter in any, other respect except the one used in the argument.
To repeat both arguments: if marriage is a constitutional right, then if there is a "right" to gay marriage there is also a "right" to incestual marriage. Therefore, the claim that gay marriage is supported because it is a "right" cannot logically be advanced without agreeing that incestual marriages should be supported, too.
Similarly, if the fact that gay marriage does not lower the number of regular marriages is an argument to allow gay marriage, then the fact that someone marrying two bricks, a dog, and a chevy would also certainly not lower regular marriages (if only because virtually nobody would want to do it, except perhaps as a joke) should be a reason to legally recognize that as marriage, too.
