I would never ban anyone for taking the "other side" of the argument. The instant you become disrepectful to another board member, I frown heavily on you and so do the other moderators here. I love a good argument and I love reading them on here. I've learned many things from you guys over the past few years.
The 2 biggest rules here IMHO are "don't disrepect your fellow board member" and "don't bad mouth any part of our local fishing industry (stores, guides, etc.) Those are best done via the PM system.
