Can you be EXTREME, yet not HARDCORE?

It depends on what you're definition of hardcore wrestling is. If Hardcore to you is using weapons I guess it's possible, a lot of high risk moves could count as extreme but not be hardcore. But there is no one set definition of hardcore, since to some(only a few though since people seem to have had their opinion changed by the hardcore title and ECW) It is just about what you do, Ric Flair going 60 minutes against someone is pretty hardcore, but involves no weapons, It's hardcore because he wrestled for one hour without slowing down the pace and punished the opponent. That was hardcore but I don't think it's really extreme.
