As Oscar Wilde so correctly pointed out all those years ago - the trouble with youth is that it is wasted on the young.
I have pointed out many times on this site that part of the joy of being a student is that your every physical need is met, allowing your planet-sized intelligence to grapple with and spout about utter nonsense that doesn;t matter a damn to anyone, and that is cared about by no-one except similar people with next to no life experience, and the hollow arrogance of immaturity.
This is simply another example of that situation
This young man is unaware of the concept of learning lessons from history, and understanding where we have been as an aid to see where we are going - his life experience, and the gaps in his education, mean that he simply doesn't understand what he is talking about.
So there is no point in his 'elders' getting all het up about his ignorance, and arrogance, they are the product of his age and inexperience.
The issue is with giving him a platform on national television to air views that could be safely applauded in his student union bar, or his local pub, and roundly ignored by anyone with the age and intelligence to understand immature uninformed nonsense when they hear it.
He is young, he will learn, and he may look back in years to come and cringe at how callow and foolish he was - as many of us do, but we were allowed to spout our nonsense in strictly limited circumstances, his ability to reach out to, and annoy, the entire wider world is the downside of mass communication.
