Maybe we need a national campaign to re-criminalize adultery? No jail time, of course, but a small fine perhaps? Just a little something to restore some of the backbone into the tradition of marriage.
I wouldn't do that but you are on the right track. "Gay marriage" is the end result of 40 years of society taking a sledge hammer to traditional marriage, starting with the relaxing of divorce laws. We haven't had "traditional marriage" in this country since the early 60s. Its disgusting. The institution, so weakened, falls easy prey to other perversions. And "gay marriage" won't be the last. After that something else will come to weaken marriage further.
No, we need a culture change to re-STIGMATIZE adultery, and to re-STIGMATIZE slutty behavior among teens, and to re-STIGMATIZE illegitmacy. These things have been glamorized in the last generation and especially by the entertainment culture. Taking back the culture will not come through legislation, so we need to focus our efforts where we can win the culture war.
