No, it would be more like watching OJ Simpson host a sports TV show. It wouldn't surprise me if he could be entertaining, and certainly he has significant knowledge of at least football, but I would not be interested at all in watching him. I would also look askance at any network that employed him in such a capacity.
I think that's a great example of what I mean. The question is why do we accept he has insight and knowledge and still reject him in the role of sportscaster? The role of commentator has nothing to do with the crime, so why does it matter?
Your "hat" example is just silly; though I know the better example of Hitler's mustache style is still looked down upon today, it's a big-time "who cares" situation - even current Nazis aren't similarly sculpting their facial hair. In the case of a pedophile mechanic, I suppose I would wonder how you'd even know the social/criminal history of your mechanic. It's true that I'd tend to avoid giving my custom to people I know to be pedophiles (or other criminals), but I don't run background checks on everyone I meet and certainly not on every employee of businesses with which I come into contact.
You're OJ example was much better. As to background checks, are you saying it doesn't matter what people may have done, only whether we know about those things or not?
I think that's correct too. She hosted the show for quite awhile and was popular during the time period the lawsuit covers. So her racism wasn't an issue for the show, or at least not detectable to her fans. So now it's come out and the great show someone watched a few months ago is, what? tainted and no longer a great show?
I'm not disputing this is how humans behave and react, I'm just fascinated that we do it so readily and without examination or curiosity.
In other words, I think you're trying a little too hard to find fault with this woman's firing. Image matters way too much in the entertainment business (and that's the business in which The Food Network competes; they're not selling food!) to set aside issues that could tarnish a personality's public reputation.
Someone earlier made a great case for firing her - she works at the will of her fans and the predicted falling off in popularity makes her not worth the money. Since her contract was up anyhow, it's a good time to boot her. I don't care for her or the show, and grant employers the right to fire someone. But the whole mechanism is still interesting.
Suppose Bill O'Reilly came out as gay. I'd predict his fan base would fall off. (Remember, Deen gets fired based on this expectation, not, as far as I know, actual Neilsen numbers). Should Billo get the boot because he's gay with the same rationale? I wouldn't argue against it. Nor would I argue against firing a newswoman who no longer looks as attractive as she used to. The same logic applies and it should. However, in some cases, there's a kind of righteous revenge motif and in others the firing is seen as an injustice.
And then we have the obverse. Wasn't Glenn Beck fired in spite of good ratings?
