Racist? Maher is an atheist who has been accused of being an Islamophobe because he considers Islam to be among the most fundamentalist of religions and the most common basis of theocracies. When the Sultan of Brunei declares that gays will be stoned to death in the town square that is surely worthy of comment – and protests and boycotts. That is hardly racism.
Misogynist? Around half of his usually-distinguished panelists are women; if not half, then certainly very many of them.
Bigot? What would be your cite for that? The virus did come from China. It has nothing to do with Asian-Americans or with individual Chinese people but it does have to do with certain unhealthy customs and with government bungling, though the latter is certainly not unique to China.
Unfortunately the Emmys have a “reality show” category, the most inane and mindless form of television in existence. Trump had two nominations in that category. Maher’s nominations were for being informative and funny.
That was the show on Nov 1, 2019 where the introductory guest was Jay Gordon, who has been called an anti-vaxer but is more of a cautious skeptic. I would have to agree with your cited article, though – even though Maher tried to focus the discussion on the vast unknowns that still exist in medicine, there was too much fodder there for nutcases to use to reinforce their anti-vax sentiment. As with Yiannopoulos, I wish Maher would stop having guests like that, although nutcase guests are really rare, and Maher often challenges them, as when Rick Santorum was on spreading disinformation about climate change. Santorum cited a denialist study about which Maher had no prior information, but took the time on the following show to provide a detailed scientific rebuttal, which I thought showed an admirable motivation to get the facts out and set the record straight.
I think this has gotten way off topic and I’m done with it. Maher is not perfect; he’s sometimes divisive, controversial, and opinionated, and many people don’t like him. To each his own. I enjoy his style of humor. Obama thought enough of him to be a special guest on one show, as have countless leading public figures from both sides of the political spectrum.
