Based on the facts in this study, why would any country want to make homosexual marriages legal, and abandon the "one man/one woman" marriage which might eliminate the mental disorder of homosexuality among offspring? To be left without a mother or father by death is truly a great loss to a child, but for the country to purposely place that child in peril of becoming gay by eliminating the need for two strong parents through manmade laws is unconscionable.
and it leads to a decline in the birth rates which is why the bible and religions are against homosexuality. eventual extinction of a civilization by not reproducing.
