Again, this is a critical distinction between liberals and conservatives. Liberals are obsessed with making sure everyone feels equal and unoffended. Conservatives do not shy away from the reality that not everyone and everything are of equal value. From the perspective of society a biologically fruitful marriage is a superior thing and deserves special status. Sorry if that hurts feelings.

I don't understand. Do we need more people? Is there a population shortage? Six billion isn't enough for what exactly?

I'd say we need more smart people.

It would be scary if the smart people stop having kids. The world would be taken over by stupidity.

Then I have a simple suggestion based on the same wide-ranging generalisations you base your reasoning on:

Make marriage illegal for all the heterosexual couples who believe that same-sex marriage should be illegal.

Um, Jesus walking on water? Talking snakes? Worshiping a book that condones slavery? Believing that there is a "God" that just popped into being out of nowhere existing beyond time, and that this idea is more likely than the universe just always existing beyond time?

The Branch Davidians called. They want their delusion back.

BTW your comments about liberals don't apply to all of us. I'd be very happy to offend you, and I'm sure it wouldn't be hard, since you seem to be a conservative.
