Harming others needlessly is hardly civil.Maybe Scalia does not need to be enlightened. Maybe he simply has a differing opinion on gay marriage. Why can't we simply agree to disagree in a civil way?
Scalia has made it clear he is "morally" opposed to treating gay people equally under the law, based on nothing more than a history of prejudice and legal discrimination. He wants to impose his prejudice, using the force of law to harm gay people for being gay people.
