P.S. I am a white male in my mid-twenties, and I will be the first to admit that being me is stupidly easy. And no, it's not fair.
Sub low thirties for mid twenties, and you got me, too. I didn't read the article (yet), but as a general critique on anger, I have to agree with you. I want society to be better. I try to make it better. However, there are probably times when I'm inevitably part of the problem, although I may not be aware so. I takes a cool and calm voice to tell me why I'm wrong, and I'm all ears, even if I end up disagreeing. Everyone should be treated equally, but it's not always apparent to those in the power position when they're being abusive. If once observes an abuse or unfair treatment, and their reaction is essentially, 'You're an oppressive pig', then most oblivious oppressors will react in like manner (e.g., 'Shut up. I treat everyone the same, so quit your whining.'). It takes talent to point out injustice in a dispassionate, logical way. (The best example I've ever read in my life was this. It's brilliant and should be read by everybody.) To the wronged, it may seem obvious that they're being wronged. But it may not be so to the perpetrator. Educate rather then vilify; that's my position.
