We’ve been redefining marriage from the day society first coined the term marriage.
Up until 70 years ago, marriage has been more about economic unions than love. There were no rights for married women, they were nothing more than property for 4,900 of those 5000 years.
50 years ago, one couldn’t legally marry a person of a different race, they were making the same arguments against interracial marriage that you are making today about gay marriage.
Once again, we have to see what are the true principles of a society, it will be legally possible to enforce a ban on bestiality because informed consent has been a cornerstone of western civilization for 1000 years. And an animal just can’t give informed consent.
Same thing with polygamy, contract law states you can’t promise the same thing to two different people. Polygamy violates this. This is more physical law than anything else.
But Gay marriage doesn’t violate any of these principles of western civilization. If you want to ban gay marriage, you will have to show how adam and steve getting married in San Francisco is going to cause you to leave your spouse and take up residence with an animal.
We have not redefined marriage—it has always been between one man and one woman.Acceptance of interracial marriage did not change the basic concept of one man one woman.
Legal contracts are made everyday where one person promises things to more than one person.
Women from the time of Moses in Jewish society, and later, in Western civilizations, had the right of inheritance of property.
You say that informed consent cannot be overturned due to 1,000 years of precedence. We are about to overturn 5,000 years of precedence. And since when, in a legal free for all that describes modern jurisprudence, would this even be a criteria once the gay lobby starts their wialing and gnashing of teeth over the “injustice” of it all.
All of us will have our society changed when the Pandora’s box is opened. We can disagree on that point, but events will overtake us whether we agree or not.
