Im a huge Dorian fan, yet if I were at that seminar, i'd be a bit dissapointed.
I noticed he is not a big fan of Arnolds, good at least someone has the guts not to kiss Arnolds ass. You can see in his face that he doesn't really respect Arnold as a person or as a bodybuilder. He just said that he brought a lot of recognition to the sport. Dorian is a straight shooter and prides himself on his integrity. We all know Arnold was an asshole in his day.
Dorian didn't do much to promote the sport except be a man of integrity, Arnold on the other hand was an a-hole, everyone that knew him will say that, he is a star fucker and skipped his fathers funeral.
