That person at DU and others who have expressed those sentiments to you I say....
We had coworkers who knew, had family/friends, or worked with people in that building and given that my other half started his career in NY, any slight change of plan could have landed him there on that day, along with several other people we knew who regularly went for meetings in the WTC. Some of those people 'we' worked with were at Cantor. They weren't monsters...they happened to trade fixed income securities for a living, many were people in their late 20's/early 30's just starting to build their careers. There is some sickness among people who would cheer for murderers as victims and try to understand terrorists, but would condemn and applaud the death of people, who died horribly I might add, whose only fault is they made their living as part of the wheel of the economic system we have in this country. They, like anyone else here, were at the whim of the policy made by failures like Clinton, Greenspan, ACORN, and the Congressional Black Caucus. I'm starting really ponder more and more just how bad of a president Clinton really was now. That his policies lead to so many monumental failures in the end. That's a poll watcher for you.
