Jim although we mostly disagree, you address the issues and your contributions are of value, Dave has a long history of trolling.

If we want to have a forum where civil discussion of serious or controversial subjects is possible, there is simply no room for trolls.
Regarding Keith, he and I are usually opposed politically, but I admire the way that he conducts himself in debate, accurate, sourced and focussed on the issue.

We have cleaned up the forum let's keep it that way
