Dave,
Part of the problem is people who only come on to argue rather than to just chat to others and learn.

That is not how I see it.
I like serious discussion including of "emotional subjects."
Is that wrong? Is that being argumentative?

I can discuss food and nature any time so I tend not to join such "chat."
is that wrong?

The problems only start when people get angry and post in anger.
Why do they?
