Pegged to the 50th anniversary of the MLK’s march on Washington, I wrote an op-ed piece on MSNBC.com about the importance of the lessons of history. When I last checked there were 53 comments. I stopped reading after the comments took an ugly turn. I mention in the article why it is necessary to fight stereotypes and I mentioned a boy in a hoodie. Who knew that the word “hoodie” could set off people in such a way? I was referring to the general sense that we judge people based on preconceived notions, not all of them correct and that yes, that applies to Trayvon Martin, but also to “Stop and Frisk” and anti-affirmative action arguments. I’ve been working in public media the past six years where the conversations and debates are civil. This wild free for all is a strange thing to behold.
