Interesting. I usually click with Maher and like his New Rules, but I think the last two are misguided whiffs. Surprised at the kudos being given. I will attempt to explain more but I am also not sober so keep that in mind.
IMO the biggest miss was correlating the shooters with the violent movies. I have never seen much of a correlation (in the book I mention that studied the mass shooters or other articles) between violent movies/games and the motivations of the shooters. If I remember right it was found in 10% or so(and that wasn't even movies, it was if they played violent video games in general or not). So I think that pie chart is pretty bad, especially if there is no mention of domestic abuse of history of child abuse. That is way more common among shooters. Per the link I always share and the book on shooters:
A new Department of Justice-funded study of all mass shootings — killings of four or more people in a public place — since 1966 found that the shooters typically have an experience with childhood trauma, a personal crisis or specific grievance, and a “script” or examples that validate their feelings or provide a roadmap. And then there’s the fourth thing: access to a firearm.
Now, I agree a bit with his inclusion of that cell phone/internet, because that 3rd bolded is correlated with their findings that especially school type shooters are fixated with other school shootings (especially Columbine). I think claiming the violent movies were a big piece of the puzzle is a bit silly, and for sure not backed up by anything I've seen overall with mass shooters.
The second thing was more of a nitpick. IMO the ones being hypocritical are the ratings boards, not Hollywood in general. I mean we have many examples of Hollywood going over the line with the sex, and hell - we have people on these boards complaining about how woke movies are, too much sexuality, etc... However, when a PG-13 can show a ton of violence and especially gun violence as long as there is no blood but you better not have nudity in it or more than one F bomb - yes, 100% there is a weird disconnect there.
That said, where he whiffs a bit again is that IMO the movies and our ratings reflect our values as a country, they don't create them. As a whole we are sexually repressed, but are OK with violence. Most parents I know freak about about anything sexual in media, but have little issue with their kids watching violent movies, even horror movies. So, yes - I agree 100% that there is hypocrisy and weird values at play, but IMO that is us as a country and the ratings and the entertainment is a reflection of us, not the other way around.
