Suppose desegregation of schools had been put to a popular vote in the South?
It's my opinion that gay marriage should not be put on the ballot in any state. Nor should civil rights such as the freedom to not be discriminated against at work or to have equal access to spousal health care benefits. America has a separation of powers, a system of checks and balances. Where is the balance of power when it comes to a "people's veto" or a bias motivated majority?
Think about it.
