I don't know, Walter; he sounds progressive to me.
The way I read his statement, is that its not a blanket statement about moving forward, it's about moving forward in a childish manner.
Not to beat dead horse, but, gay rights would be a perfect example.
Homosexuals should have rights. They should speak about their sexual orientation, and advocate for their family unit, and demand equality in the eyes of government. Where you cross the line from progressive into adolescent, is when you don your fetish gear and flounce down the street, shoving your sexual activity, rather than your sexual orientation, in people's faces. The church, and most conservative minded people, will never tolerate the adolescent level of lashing out at the status quo through shocking behaviour. And they shouldn't, in my opinion. I'm sure I could drag up a plethora of such examples where the idea may have merit, but the extents it's taken to, make it flawed by its execution.
