Bill:
For the record, I agree with the way you and the other mods keep this forum under control. Even I have slipped and posted inappropriate comments, which were handled in a polite and civil manner.
There are always three major hot-button topics; politics, religion and sexuality. No matter how one would try to moderate such discussions, it is far too easy to allow them to degenerate into major flame wars.
If you'd like an example, take a look at the forums on powerlineman.com {Mods: feel free to edit this direct reference if you deem it necessary.) I'm not knocking the site or it's moderators, but thier discussions frequently get quite out of hand, with personal insults flying.
Even designating a separate area for politics can still result in a lot of misunderstandings and bad blood.
So my vote would be for no politics, thank you.
Let's keep this site great!
