The results, including the public’s yawn, come from decades of non-Bible based (ie, relativistic) media and education. We just kept our heads down, attended church, and saved for kid’s college and for our retirement, and here we are!
The results, including the public’s yawn, come from decades of non-Bible based (ie, relativistic) media and education. I would argue the opposite: it comes from the fact that too many of the opponents of so-called "same-sex marriage" voiced their argument in ways that could be spun by opponents as "trying to cram religion down their throats".
If opponents of SCSSM had instead focused on a couple more important principles, I think they would have fared much better:
- The joining of people into long-term heterosexual mating pairs predates religion, predates governments, predates written communication, and might quite plausibly predate Homo Sapiens [given that many animal species behave similarly]. Religions and governments acknowledge such relationships, but that does not mean that they create them.
- Marriage has always been, fundamentally, centered on recognizing the legitimacy of an exclusive sexual union between individuals. It is hypocritical for proponents of SCSSM to simultaneously demand that others "keep out of their bedroom" but simultaneously demand recognition for what goes on there.
Any argument whose validity is predicted upon the Bible will be irrelevant to anyone who does not regard the Bible as a perfect source of truth. On the other hand, I really don't see any good counter to secular arguments like the above.
