Justify? No, it's exactly the opposite. I listed homosexual intercourse together with cohabitation, abortion, etc. in order to show that NONE of them are justified. The males and females, by their depravity, degraded marriage even before gays decided to adopt pseudo-"marriage" as part of their agenda.
Through most of the 20th century, gays and sexual activists were generally anti-marriage. They described it as a regressive, bourgeois structure. They didn't make a strategic pivot toward "marriage" until very, very recently. The first laws in history enabling same-sex so-called "marriage" were not enacted during the first decade of the 21st century.
Really? I didn't see that in your post.
Cohabitation - contraception - divorce Wrecked marriage before the gays even got interested in camping out in the rubble.

S&G didn't consider marriage because there was 'no freebies' in it for them back then. Evil knows no bounds when it comes to attempting to mock God - so now they will mock those who do honor God - while getting their 'married' freebies, and can by 'law' now. And that is how evil had the open door - simply make ourselves equal. man/man or woman/woman will never equal man/woman.
