Journalist and commentator David Sirota has an interesting piece about the reaction to some statements about the role of white men as the typical killers in the mass murders like the ones in Columbine, Aurora, and Newtown which he made in an MSNBC commentary and interview with Chris Hayes:

I said that because most of the mass shootings in America come at the hands of white men, there would likely be political opposition to initiatives that propose to use those facts to profile the demographic group to which these killers belong. I suggested that’s the case because as opposed to people of color or, say, Muslims, white men as a subgroup are in such a privileged position in our society that they are the one group that our political system avoids demographically profiling or analytically aggregating in any real way. Indeed, unlike other demographic, white guys as a group are never thought to be an acceptable topic for any kind of critical discussion whatsoever, even when there is ample reason to open up such a discussion.
