It's both rational and correct. Because you don't agree is why you claim no rational basis, you've been labeling 'irrational' and being forced to assume this or that and name calling since you got here. You're an agenda driven Leftist, anyone objective can see this.You have yet to provide a rational basis for your position.
I already did, in fact, you were unaware of much on this issue as well.I asked you to prove me wrong.
The rationale is that marriage is a unique relationship. Both for the purposes of defining our culture, but in raising children, and in defining families. Women change their names, children take the last name of the father, we don't define any other relationship as important or critical.
You haven't been anywhere near right, there isn't any reason to prove you wrong, a school student could do it. Your argument is...."there's no opposition that makes sense to me..so....there is no argument that should make sense to anyone else either....I'll have to assume you're all homophobic evildoers."
