There weren't good arguments though, it was a rehash of the same 'debate' forty years prior on whether people of different races should be allowed to get married.
You know, 40+ years ago, if you brought up legalizing gay marriage many would have seen it as attacking interracial marriage. Even 5 to 10 years ago I met many people who held the view that it was an insult and attack on interracial marriage to bring up gay marriage.
Today, if I bring up possible future rehashings, I think people would react the same, thinking instead I was attacking and insulting gay marriage. I wonder how long in the future before we see history repeat again.
