Some well-thought-out opinions here (by which I mean they agree with mine
).
I have no problem with gay marriage. Canada has moved in that direction (with BC helping to lead the way), and that's fine with me. I know a gay couple (who had a civil marriage ceremony) who are great parents. They adopted two brothers who had gone through half a dozen foster parents in two years, and were going to be split up. They've had the boys for over three years now, and provided them with the family stability that the boys never had. The boys are now well-behaved and infinitely happier.
Although I'm skirting the dreaded and banished religious discussion territory, I should point out that all four people in this family are members of my church.
I get the feeling that this whole issue will blow over in a decade or two. I see a lot of the same arguments that were raised re: divorce, and divorce is well-established and practically an industry in and of itself.
Bottom line is that the idea of gay marriage represents a change in social attitudes that some people are not comfortable with. It's not surprising that an ancient prejudice and the current symbol of Other are combining to prove a formidable obstacle to gay marriage.
