I am an ordained minister, I live in the USA, and I grew up as a very conservative Southern Baptist in Alabama. Knowing that...
I was recently asked if I would ever marry a gay couple. My answer was, YES. The person that asked me that was taken back by my lack of hesitation in my answer. They could not believe what they just heard.
After they recovered from the initial shock, they asked "why?" This was my answer:
In this country, there is a separation of Church and State. The government (State) can't dictate to the Church how it is to be run, what to believe, or who can serve in a clergy-capacity. By the same token, the Church can't dictate the law to the government, regardless of what the issues might be.
I went on to explain that not everyone in this country is a Christian, so why should everyone be subject to Christian "law?" The US Constitution grants rights to all of its citizens, regardless of race, gender, religious beliefs or sexual orientation. Gays have the exact same rights as everyone else, and that includes being married.
That person was speechless. I added that I personally do not agree with a gay lifestyle, but it is not my place to discriminate or judge. To each their own in life, liberty and the pursuit of happiness.
At that point they tried to make some type of come back and the best they could was to mutter something about children seeing two guys kissing in public. While I understand the confusion that might cause in a child, I actually can't recall a time that I have seen that happen. If it does, I will deal with it in my own way with regard to my children.
The last thing they mentioned was how gay men would be sexually abusive to children. I stopped them right there and explained that there is a HUGE difference between being gay and being a pedophile. People can be gay and have no attraction to children what-so-ever.
They walked off.
