It's more a question of what you do that Mark doesn't.

Mark comes across as a refined, intelligent, and thoughtful gentleman, with serious concerns about the wellfare of the chipping hobby.

You, I am sad to say, come across as a belligerant, self centered, ranting bufoon, who lashes out at evryone dares to contradict your view of things, even when you are not part of the discussion.

Your rambling, incoherrant, childish posts, full of unfounded personal attacks and veiled threats, have me wondering if you are manic/depressive or a substance abuser.
