Aon is extremely proud of their "diversity" program. Although it encompasses all "protected classes", it's primarily a platform to promote the LGBT agenda (hence the award from Human Rights Campaign). If you fall into one or more protected classes, you're considered golden. If you happen to fall into the (only) unprotected class (white hetrosexual male) and not in a senior management position, you're viewed as second rate.
Not familiar with Eugene Clark, but well aware of the loss that Aon took on 9/11.
