I think Jones' style of talking is geared toward people who are working from a script and trying to manipulate their audience by painting their guest or opponent into a corner with loaded questions. I think Morgan's purpose was to appeal to one segment of society who watch his show, but Jones had a completely different purpose.
It's sort of like election politics and the swing voters. There are probably about 60% of the US population that are completely orthodox and truly believe everything on TV. There's 20% who think there might be something amiss, and another 20% disbelieve the orthodoxy and have an inherent mistrust of authority. Prior to WW2, these figures would have been reversed. Morgan's audience is mostly those in the 60% and a tiny portion of the 20% who think something is amiss. They are the swing voters whose opinions were being competed for by Morgan and Jones.
Morgan is normally the calm, fatherly figure of the evening news figurehead that we've become familiar with since the advent of TV, whereas Jones uses emotion and loudness to shock people into sudden awareness, although it is a turn off to many.
I think Morgan's very emotional and discourteous treatment of Larry Pratt of Gun Owners of America a couple of weeks ago, as well as Morgan's confessional article about guns in the Daily Mail a few days later, indicate he's probably sincere about his views on guns. However, his naive revelation that guns are "killing machines", really? wow, shows that he's just a talking head who likes being in an elite position, but he does not actually know the issues. Mainly, he knows how to manipulate his guests based some other interviews I've watched.
His attempt to save face from calling Larry Pratt names was to invite Jones on and then mistakenly expect him to eat from his hand, insisting ridiculously that a debate is Morgan asking Jones simplistic questions while Jones answers them in sequence to validate Morgan's conclusions, like his usual Hollywood guests like to do, which was shown to be a massive strategic error.
Jones' behavior on Morgan's show was completely typical going at least back to 2007 when Jones lambasted the Rothschild heir apparent when Rothschild claimed that Jupiter was heating faster than Mars because Jupiter was closer to the sun.
I loved it when Jones switched to his upper crust British accent. Fantastic entertainment! In case you can't get to youtube, you can watch the entire 13 minutes here
To answer if Jones is erratic or crazy, watch his documentary films, like Endgame (2007), Terrorstorm (2005), or The Obama Deception (2009), all of which he gives away for free on the internet. Then you can judge for yourself.
The more you love, the more you live.
