That's silly like the British market was going to yield so much revenue from magazines , Especially considering the US was the mecca for bodybuilding and it was niche market and even more so in the UK. It defies logic , Shawn Ray was on more magazine covers than Dorian by far. If Joe Weider was going to hand pick people to win he's be an idiot not to pick Lee Labrada, Handsome , articulate , College educated married family man with an " attainable " physique much more marketable than a pasty Brit who was a " skinhead " and disappeared back to the UK after every contest.
I think Weider did make Dorian remove the skin tattoo on his forearm, and was questioning him, asking if he was an antisemite and so on. Well, Dorian turned out to be some kind of "antisemite" after his career, to his credit IMO.
I think marketing did come in for his decision to sponsor him, give him a contract. My guess is Joe was influenced a lot by Peter McGough. Despite him being a non-show most of the year he became a fan favorite at least. And he became a favorite on the podcaster circuit, despite his controversial views regarding you-know-who. He must be personable enough I guess, despite not being a loud mouth.
