I always find it fascinating that some of the greatest advances are often made in response to an attack. The article mentions Anita Bryant who, although temporarily successful, helped create an organized opposition. And while the shooting of Harvey Milk was a tragedy I wish had never happened it did help propel LGBT rights forward--although I think things still would have moved forward even if he'd lived.
Most telling, though, is the picture at the top of the article of a man holding a sign that says "We are your children." Even though there are still too many parents willing to throw their LGBT children onto the street the opposition to LGBT rights is losing ground because they're not targeting individuals. They're going after families.
