Jimmy Joe, this is a very, very, incredibly and painfully simple situation: You have committed the fallacy of the excluded middle, by claiming that if you change ONE thing of a law, you must change ALL things.
Let’s look at an example. Suppose, for a moment, hypothetically, that there were a law that requires all cars to be colored blue. This lasts for a hundred years, and everybody on the planet enjoys the sea of blue on the congested 405. Then, one day, a revolutionary - that probably smoked reefer in his younger days, the cad - comes along and proposes that cars be allowed to be colored blue OR red… red! Gasp! The horror!
Well, along comes Jimmy Joe, saying, “Why, if you allow RED, then clearly you must allow GREEN and PURPLE!! And, dare I say it, ORANGE!!”
But then the reefer-smoking revolutionary - let’s call him, oh, SPOOFE - responds: “Why?”
Sayeth thou: “Why… because… because!”
Sayeth SPOOFE: “What makes blue intrinsically superior to red?”
Sayeth thou: “Because that’s how it’s always been!”
See, buddy, marriage is a funny thing… words and definitions are funny things, because they change as the populace changes. If the populace suddenly decides that “chair” means “table”, well, that’s the way it goes. There’s nothing inherent to the word “chair” that requires, by any law, natural or otherwise, that it mean “a thing to sit on”. That’s just what is COMMONLY accepted.
Of course, words change definition. Language - and the species that gave rise to it - is notoriously flexible and fluid.
To state that people who support same-sex marriage must also support dog-human marriage, or group marriage, is akin to me stating that anyone who disagrees with same-sex marriage must also believe that people should be REQUIRED to be married, forced to be married.
Of course, you don’t really believe that marriage should be mandatory, do you? No, of course you don’t. Because extrapolating that conclusion from what you have stated in this thread would be insulting, now, wouldn’t it? And I don’t want to be insulting. Of course not. 'Tis not the SPOOFEy way, grasshopper.
