By the way... In this context and your apparent refusal to accept what is self evident, I'd say you're the one being narrow minded. Do you feel any guilt? Is it why you're so open to the idea of destroying marriage further? In Sweden a once vibrant family culture, the intact families are in the minority already. In 10 YEARS, they have become the minority in favor of out of wedlock child births.
SSM is only a reason to avoid such a future for ourselves. Tell me, what is the upside to gay marriage?
