Really? How? What is it about not allowing discriminatory business practices that destroys the ideology of bigots? No one is making bigotry illegal here, just declaring that bigotry is not grounds for refusing peoples' business. They can still be bigots if they like. So let's put the kibosh on this "you're using the state to destroy ideas!" business. We're using it to eliminate discriminatory business practices, not ideas.
Why religion should be an excuse to treat certain citizens as second-class eludes me.
