It's well-worth a read now and archiving for future reference.
To get you started:
In his book The Future of Marriage, David Blankenhorn, a liberal, gay-rights-supporting Democrat and self-professed “marriage nut,” offers this sociological principle: “People who professionally dislike marriage almost always favor gay marriage.” As a corollary, Blankenhorn adds: “Ideas that have long been used to attack marriage are now commonly used to support same-sex marriage.”Read it all here.
Blankenhorn provides almost irrefutable proof that this is the expressed agenda of many—if not most—professional advocates of same-sex marriage. Other scholars have noticed the same and have attempted to present the public with the facts about the less-than-hidden agenda to use homosexual rights to deinstitutionalize marriage and to separate sexual exclusivity from the concept of “monogamy.”
Since the agenda is an open secret, how has this anti-marriage program been able to advance to the level of public policy? And how did it happen so quickly?
All issues fall somewhere along this policy continuum, which can be roughly outlined as: Unthinkable, Radical, Acceptable, Sensible, Popular, Policy. When the window moves or expands, ideas can accordingly become more or less politically acceptable.
