I hate to keep pulling this back but this shouldnt be about philosophy, theology or theoretical physics.
This is about actual law.
the 14th Amendment allowed the federal government to throw its weight onto the states, but it isnt an absolute right.
Can anyone show a clear harm that comes from not redefining marraige to include same sex couples? This isnt riding a bus or eating in a restaurant. This is having to fill out extra forms for a civil union, as opposed to a marriage. No one is preventing parties or regestiering for a shower. This is a technical issue, not a civil rights issue,
We need to draw a line in the sand and let government "Of and by the people" have some meaning. We cannot allow a handful of people tell millions how to live!
