Yes, I agree with that reading of history, but just because things have been a certain way, doesn't mean they have to be that way. I concur that the historical precedent for the SCOTUS is to stand in the way of progress, or often to cause regression, but that doesn't mean we have to quietly accept it. Especially if and when there have been historical departures from that trend that demonstrate things can work differently, and work well.
(Not trying to be confrontational, just trying to prevent a nihilistic reading of your comment.)
