> but Jim has a way of going so extreme on those last 10% that it often ruins the message.
That's exactly how it works on the other side.
Jim does what he does because he knows it works. I'd recommend if you're at all interested in reading about politics or journalism, checking out "Blur: how to know what's true in the age of information overload". It covers this topic very early on.
The strategies Jim employs in his videos and journalism are the ones necessary, because they're the exact same strategies right-leaning political candidates and leaders use to gain such a huge following.
I'm summarizing, obviously, but basically: People on the left side take other sides for granted. They think that they're better than the other side, that they're smarter, and that's their greatest downfall. They don't realize that the right aside is just as smart, maybe even moreso, and they also know how to emotionally manipulate.
The repetition of certain terms, the creation of new terms entirely, down to the certain ways Jim portrays himself or says terms like "Triple AawaaAAAaaaa". The topics that frequently pop up in his videos. Those are the exact same strategies used in politics.
You repeat them, you create new terms, and you drill the new terms into the heads of your audience. You create emotional connections. "The War on Terror" sounds a lot more emotional than going to foreign countries and killing civilians. "Carbon Emissions" sounds a lot less scary than global warming. You create emotional connections and you encourage your audience to do it as well. You keep them informed and you keep them rallied to your side. You manipulate them.
People that just brush off Jim's style as abrasive aren't doing themselves any favors in the long run. If they see this video and realize that everything Jim says is right, that's good, but if they look at Jim's videos and brush him off as being too eccentric or exaggerated, they're doing the same thing that happens in politics - brushing off right-leaning representatives as too crazy, too uninformed, too "good ol' oys". They assume that they're better than them. They aren't.
