I saw that live online chat Monday. I was at least happy to see that Clifton, VA was rebuked by not only the chat host but also a few other participants. Of course, there is no way of knowing whether other similar nasty posts weren't allowed to appear.
This past Monday's chat transcript is still available if you feel like registering.
