A new variation on the "straight people are terrible" argument against marriage equality:

On the surface, abortion and same-sex marriage may seem unrelated. However, as explained in an amicus brief of 100 scholars of marriage, filed in the pending Supreme Court marriage cases and summarized here, the two are closely linked in a short and simple causal chain that the Supreme Court would be wise not to set in motion. Even in the short time that same-sex marriage has been officially recognized in some states at home and abroad, man-woman marriage rates have declined. In a nutshell: A reduction in the opposite-sex marriage rate means an increase in the percentage of women who are unmarried and who, according to all available data, have much higher abortion rates than married women.

More than 100 "scholars" signed on to the amicus brief making this argument—mostly "professors" at "Christian" "universities."

Religious conservatives have already argued that straight people will stop getting married if gay people can and that marriage must be reserved for straight people because only straights can get pregnant by accident, and without the special inducements of marriage (a big party, a special cake, a honeymoon), straight people won't take care of all those babies they're having by accident. Now they're arguing that straight people will abort their babies if gay people get married.

Man, straight people are terrible—why were they ever allowed to get married in the first place?
