@hawkeye10,
Oh, so you know that myriad of hetero divorces isn't effecting the "family," again with yourown myopic definition from the Idiot's Dictionary, or its effect on the community including the churches. You know that gays are very transitory in their relationships, much like the majority of single heterosexuals who outnumber them? Where's your proof.
The main entry from Merriam Webster is:
1: a group of individuals living under one roof and usually under one head : household.
In other words, a family can consist of two married people, their relatives and friends.
When MW gets down to family consisting of two parents raising their children (5a), there has to be an arbitrary rider as to the sex of the two parents, and that comes out of religion.
Who is the "we" who don't know there if there will be problem. You're still writing as if you are slipping back into the past and are unwilling to shake it off, a stagnation of mind, body and spirit.
I'm willing to guess the "who" is your own little commune, thus stating that the meaning of family may become meaningless -- better check all the definitions of the word. You're already picking and choosing what it means.
It makes me wonder what human contact you have, or are you stuck on the Internet blogs and forums, letting them make up your mind for you?
Society is built around communities consisting of several different kinds of families. The congregation of a church is, by definition, a family.
Your semantics are constricted by the narrowness of mind typical of those against gay marriage -- reasons expressing the problems stuck in religious morays going back through history. It's time to get out of the rut -- or climb aboard a time machine and go back to the era you consider wonderfully perfect. I'd set it for you -- the Spanish Inquisition.
