Mario is right. The state has and should have an interest in promoting stable family units.
I'm all for keeping gays out of that tho. You give an inch into those people and they wanna flaunt their ideology all over, pretend to be victims, AND once they get their way they adopt other "victims" (trans, non binary, queer two gender blah blah) only to keep up their victim larping.
I'll take gays seriously as soon as they stop demanding they have their faggot flags all over my city, flaunting their faggotness, etc.
