Don...Participation in a "marriage" ceremony does not guarantee fidelity or monogamy. I know of several married heterosexuals who have been unfaithful to their wives or husbands
An extended family structure is much more likely to keep men and women on the "straight and narrow".
"Homosexual "marriage" will make very little difference to male homosexual sexual transmission rates, even if they remain monogamous, the uptake RATES are so small that it is impossible for them to have much affect. This legislation does much more harm than good.

It is really a smoke screen to obscure the true nature of male homosexuality...hedonism, promiscuity and risk taking; also a double edged weapon as the "conservative" church can be attacked for opposing "equality"

It is in fact a "liberal" attack on conservative social values.
