I just reread this great piece about Mary Bonauto
in the NYT Magazine last week. The last paragraph is exactly right:
Looking back 50 years to Brown v. Board of Education, most Americans have no difficulty in distinguishing the legacies of Thurgood Marshall, Martin Luther King Jr. and John F. Kennedy from those of the segregationist governors Orval Faubus, Ross Barnett and George Wallace. And 50 years from now, the odds are that Americans will have little difficulty in distinguishing the legacies of Evan Wolfson, Mary Bonauto and Gavin Newsom from those who oppose gay equality. As Kevin Cathcart asks, "Which side of history do you want to be on?"
Mitt Romney even had to use a segregation era law to limit gay marriage to Massachusetts citizens.
