Go up to Finlay or Regal or JBL in an airport, ask them if it's 'fake'. See what happens. Better yet, search out someone like Vader.
It's only fake when WWE tell us it's fake. It's real when WWE tells us it's real. That makes it different from CSI and 24, where there is no grey line. When a character dies on a drama show, a- it's understood that it's fake, there's no grey line that makes people believe it is real (case in point, the amount of people who DID think it was real, when did that ever happen with CSI or 24 or House or something like that?) and b- it's not treated in the same vein as a real death would be, which is basically what WWE have been doing.
Besides that, Wrestling isn't like acting, otherwise wrestlers wouldn't take bumps, stunt-people would.
Piss off some bully-thug like Vader. No thank you. If he can't admit that everything outside the wrestling itself is scripted than fuck him.
