But there ARE laws specifically instituting discrimination against gay couples wishing to be married, right?
Yes, just as there ARE laws specifically instituting discrimination against polyamorous and incestuous couples.
The question DFLers need to ask is, is mankind ready to redefine an ancient human institution that is biologically natural and universal?
It's important to consider that in states where same-sex marriage is legal, public schools are required to teach impressionable children that homosexuality is a normal and an equally valid alternative to heterosexuality. This new and untested social experiment, which goes against humans procreative instincts and natural order, will have profound negative social, economic, health, and evolutionary consequences.
The LGBT movement would like you to believe that same-sex marriage is only an issue concerning two people who love each other, but that is far from the truth.
