If you enjoy arguing does it count as an argument? I love a good bashup.
Does teasing count? I see a lot of "arguments" which are just the result of misunderstood jokes between people with different sensitivities.
Finally - as a reader ( I read far more than I post) the arguments are stellar. Keep 'em coming.
