bryan, it means that he's trying to take over the list with his

You are correct. Let me translate what he said for the rest of the list:

"Bienvenue Jean-Guy! Je suis un des moutons noir de cette list.."

That says "Those Americans are so stupid. You'd think they'd at least learn
one foreign language. Anyway, I have those idiots fooled into thinking I
love these Vanagon things when in reality I drive a Toyota. I just love
ranting on this list for those poor suckers that drive Vanagons."
