@hawkeye10,
I think if Duck Dude had been expressing these kinds of views on his reality show, it would never have gained the popularity it has.
It remains to be seen whether viewers. now knowing how this man thinks, will be too turned off, or offended, by his views, to still enjoy the show any more.
I can no longer watch Mel Gibson in a movie, even his old movies, because of what he's revealed about himself--it definitely interferes with my ability to enjoy any of his performances, I have an emotional reaction to the man.
On the other hand, I never agreed with any of the protests and calls for boycotts of Vanessa Redgrave's films because of her support of the Palestinians many decades ago, even though I didn't agree with her views at the time. And it never interfered with my ability to enjoy her work--I think she's a fantastic actress.
So, whether Duck Dude, and the rest of the clan, remains popular may depend on how viewers react to him now.
