..........what?
Did you even read the article at all? It has NOTHING to do with removing/denying/retconning the Silver Age. It's about how modern writers are all about trying to "recreate" the Silver Age as they remember it: through the nostalgia of childhood memories. When, in fact, the Silver Age was not as innocent and morally perfect as their memories lead them to believe.
It has nothing to do with denying the power of the era itself. It has everything to do with acknowledging the historical facts of the era, not the romanticized memories of fanboys...
