What Professor Runciman has done with some success is that he has got people to talk about the subject. I doubt that if he had simply said our democracies have become structurally unbalanced there would be any discussion of it on this board or elsewhere. Hyperbole was often used in the Bible to get people to think.
@Earnest, he is not using hyperbole. It’s not like he is exaggerating the claim that youth are underrepresented (as in, “The youth are not represented at all in this country”). This is a policy suggestion - a proposed course of action. He says it is to draw attention to a problem. It is not. He wants to shift the voter base to younger, less responsible, more pro-government voters. He wants to get the political result he believes in. And if the stupid, dumb old people can’t get with it and vote for what is clearly the best policy, then maybe we aught to get the six year olds to do it.
And really, what useful discussion has this spurred? The only discussion this seems to have started is on the topic of his apparent mental retardation.
