The State sanction of this ideology will promote its spread within the rest of society, affecting true natural marriages as well.

How will it "affect" them? How will that effect be enough to destroy the institution?

We have seen the rise of the utilitarian view of marriage over the last thirty years in the rising divorce rate and all of divorce's attendant social ills.

The promotion of homosexual "marriage" utterly destroys what's left of the notion of marriage as a natural institution. I can only see this legislation as speeding the decline of natural marriage.

Certainly, at least ideologically, the State will have destroyed the institution, at least on the natural level. Marriage will only survive in the churches.

This will represent a devastating blow to the health of society.

Certainly, at least ideologically, the State will have destroyed the institution, at least on the natural level.

I don't know what "ideological destruction on the natural level" means. Will men and women still marry outside the churches?

Marriage will only survive in the churches.

So it won't be destroyed.
