I do take your points, Hils, and which are very good ones. But they don't necessarily lead to the conclusions you make.
eg. Better not make any movies with sophisticated plots then, eh? Because nobody is ever going to be able to understand them. That is so 'not so'.
If you regard JRM's personal views in a way which makes him a quite 'quirky' kind of a guy, then you begin to find out from what he has to say, that what he does have and in spades, is a very charismatic and likeable personality. He is also very brave and strong in his personal beliefs and that's what we want our political leaders to have. Most people will allow him the pleasure to have whatever personal beliefs he wants - so long as he doesn't want to ram them down the throats of others. He is a political giant par excellence, too.
The biggest question to ask, is, "Does he have the brain power, oratory skill and political strength to lead the government?"

He is a very, very 'with it' guy. And he relishes political debate and usually wins you, the observer, over with his simple take on things.
With his usual political skill and charismatic wit, here he is hosting a spot on LBC radio:
