Huge. Huge. Mistake.
Whether it's DOA or not, it's still a call to enshrine intolerance in the constitution.
Let me try to get this straight: it's ok for the government to tell people who they can and cannot marry, but it's not ok for the government to set down guidelines as to what a person can and cannot drive (eg, Neons are good, SUVs are bad).
Astonishing and absurd.
