I notice the pressure on Facebook to remove offending Nazi imagery, but I think it is best to have the truth out there. I know Facebook is only a For Profit set up and so there may be reasons for it to exclude this or that to appease its advertisers, but really, Nazism is as alive and well as it always has been, as are the other faults in Humanity, per se. I would suggest they just let it be. You can't hate something if no one tells you about it. There can be very good reasons for some of our hatreds and we don't learn more by knowing less about ourselves.
