What so many keep doing trying to compare gay coupes to pedophilia and bestiality and rape keep leaving out is, two consenting adults. End of story, not victims, not animals, not corpses, not children.
Two consenting adults who love each other and want to live together for the rest of their lives. No Crime, no fraud, no hurting others. Two people who want the same lives as their neighbors and the same shreds of happiness than anyone else wants out of life.
And No, civil union does NOT carry the "same" privileges as marriage. I cannot speak for other counties, but most US states that have banned gay marriage have ALSO banned civil unions as well. Some have gone so far as to ban you from leaving your own estate to your same sex partner. As apparently leaving your money to the church is perfectly reasonable. But leaving it to your partner is a "benefit of marriage" This is not a defense of marriage, it is a religiously oriented attack on citizens.
You don't know how few rights you have till the person you love is in the hospital and unconscious, and you are not allowed to visit because you are not "family". I've been there. We owned the same home, we had been together for 15 years, but I wasn't allowed to know how she was doing, as I was not "family" and had "no interest". I wasn't even able to find out what hospital she had been moved to. "A nurses aide finally risked her job to tell me secretly or I might have had to wait days"
There is an organization in The US state of Minnesota called Project 515. It is named this for the 515 "and counting" ways gays and gay couples are discriminated against in Minnesota, We are a progressive state and Minneapolis has civil unions. Yet it is still as bad as that. Now they want to write the discrimination into our states constitution.
There are a lot of us. We are people, and we are "married" in all but the paperwork. And we will not go away no matter how many laws try to make our relationships illegal. Take our rights, take our legal protection, claim we or our relationships don't exist or are "disorders" and we will continue to exist. And in the end we will prevail. I'd like to believe than love is stronger than hate. And in the end that's what it is about. We love each other and the people who have nothing but hate want us gone, by legislation, by violence, or if nothing else by defining us out of existence. But in the end we have one argument they can never counter. We love each other. And they hate us for that. And in the end the hate and fear is all they have.
