Hicks, like Nietzsche, are crystal clear that, at its heart, postmodernism is nothing but destructive, deep-seated anger and resentment. It focuses on tearing down existing structures with no intention of positive rebuilding—destruction for its own sake. In a religion sense, it is the creation of hellishness for its own sake.
You are right to point out that there's a large element of that on this thread.
Thanks for the link.
