The best response to someone trying to stir up a hornet's nest is just to ignore them. Pitching rocks back in the direction of the nest just stirs things up to no purpose. It's a forum, of course and all opinions should be welcome. That doesn't mean that all opinions should be agreed with. That's OK and we're all best served when the issues are honestly and intelligently debated. When the rhetoric starts to become personal though, this valuable forum once again devolves into a version of Flightinfo.com.
