How? By destroying the building block of society, and replacing it with nothing more than straw.
To redefine marriage ? the very core of what we know as family ? is to wreak havoc on every other institution that holds our country together. From the legal system, to interstate commerce, to health care, to your neighborhood, everything would eventually fall apart. Why? Because the nuclear family ? starting with the marriage of one man and one woman ? is the very foundation of the entire human race and every single civil society since the beginning of time.
Ask the leaders of Old Europe. There, thanks to readily available abortions and wide acceptance of homosexual families, birth rates have dropped below what is known as the "replacement level" meaning that in the future there will be insufficient numbers of workers to pay, through their tax dollars, for pensions and medical care for the elderly.
As a result, to maintain the social compacts established in those countries, already exorbitant tax rates must be raised significantly ? crushing economic growth for decades or longer ? or immigration must be encouraged in amounts so large that France won't be France and Germany won't be Germany anymore. The problem is real, and it's happening now.
Massachusetts Gov. Mitt Romney noted in a recent op-ed in the Wall Street Journal that there are many "compelling state purposes" in limiting marriage to the union of one man and one woman. For one, societies must produce physically, emotionally and morally healthy children. And, as literally millennia of experience have proven ? and your own God-given common sense tells you ? the best way to do this is through traditional marriage.
When four activist judges in Massachusetts decided that to uphold traditional marriage creates a "discriminatory status for same-sex couples" they unlocked a Pandora's box that if opened will result in unending grotesque distortions of the institution of traditional marriage.
