Keep hearing conservative bigots in the media say Gay Couples cannot have children.
What century are they living in?
So what if they can't have children. Federal law does not require you to have children to file a married tax return, to receive Social Security survivor benefits, or to qualify for federal employment insurance benefits.
"Fags can't have kids" is a total red herring.
So is your post.
The expectation (not certainty) that most marriages will result in off spring is a fundamental interest of the state in fostering such unions.
