Probably because 90% of them are Star Trek and Reading Rainbow fans. They are a stubborn lot. They are who got him there and no ones gonna change their minds no matter how good or bad he did.
I'm a Star Trek fan, too. And the last thing I want to see for anybody connected with Star Trek, whether he or she is a series lead, an extra, or a grip, is for that individual to make a fool out of himself or herself, by trying to do a job he or she is not cut out for.
At this point, I don't know whether Mr. Richards is a maligned good guy, or a whitewashed bad guy, with respect to the lawsuits. One rather telling comment I noticed was that working conditions for the models on
The Price Is Right supposedly improved during his tenure, that they were treated as human beings, rather than just almost-anonymous eye candy, with host and models forbidden to interact with each other. No opinion on the veracity of that, but I think it was under his tenure with
Wheel of Fortune that, when Sajak had his unexpected medical leave, Vanna White hosted (and did a better job hosting
Wheel than LeVar Burton did hosting
Jeopardy).
As to Dr. Bialik's controversial attitudes, some of them appear to come from her religious background, and appear to be considerably more moderate than what I'd see from an actual fanatic. I was rather slow on getting my COVID shots myself (hoping to minimize, or entirely avoid, having sharpened steel tubing inserted in my hide), and I've had exactly one flu shot in my life (and THAT was for the safety of my then-slowly-dying mother; the flu hardly affects me at all). And she's being hired as a game show host, not elected to a legislative seat.
