Liberal Humanism: A New Kind Of Leftie??

I'll admit when I first heard the term "Liberal Humanism" I pictured a new wave hippie of some sorts just diggin' lit. Of course my presumption was wrong and I was introduced to the wonderful world of appreciating literature. The ideals seem to be pretty sound, and I can appreciate a good book without having to tear it down, but I wonder just how far can this approach take us. This approach is not new so I am sure that it has some credit, but what does it all mean? I find that the 10 tenants or whatever they may be seem to limit an approach that tries not to tie literature down with limits and boundaries. I may have read into LIb. Humanism wrong, but it seems old, dated, washed up. Every time I think of this ideal Liberal Humanist I can't get the image of Robin Williams tearing up books out of my head. Maybe that is the root of my dimay...
