Oooh, now I'm on a roll

A Colorado court has ruled that girls as young as 15 (and possibly 12) can marry under common law situations. As far as I'm concerned this is legalized pedophilia. The only silver lining I see to the rediculus Anti-Gay Marriage Amendment is that defining marriage as between man and woman will protect our children. But what I don't get is why people are so concerned about label two adults give themselves, but don't seem to care at all about the real ramifications of allowing 15 year old girls to marry 38 year old men?
