The rational basis for banning gay marriage.


What is it? I think the strongest argument is probably:

- The government has an obligation to act in society's best interest;
- It is in society's best interest for citizens to procreate;
- Children are more likely to be productive citizens when they're raised in homes with both a mother and a father.

But gay couples are already allowed to adopt (along with single people, etc), and surely adopted children are better off in homes with gay parents who are legally bound to each other than in a home with gay parents who aren't. A legal contract would either be neutral or increase stability; it wouldn't decrease the stability or longevity of a union.

So what's the rational basis for banning gay marriage? There's a good discussion about it here.
