Main forum has a significant number of non-cycling chats - nothing wrong with that, friendly. When you have a wide range of chats on unconstrained subjects some will be more controversial and some forum members don't like controversial discussions (where different posters have strongly differing views).
So, to accommodate everyone, more controversial views are sectioned off so everybody happy.
Personally I find most of the discussion interesting and useful, interesting to understand how any why people hold differing views to my own. Occasionally daft "oh yes you did, oh no I didn't" starts (I'm bound to gave been in one or two) but encouraging that they resolve themselves without any authority intervention.
