I can understand that process, but for myself, I usually read his passive aggressive output with interest and try to understand what motivates him... Every decade has a new zeitgeist, that moves and tries to control us. Some people become possessed by the geist of there youth and others pick and choose bits as they're go, usually the bits that make there personal circumstance better. In your mans case, its more unusual and he seems to actively dislike the past and is rarely a foot, outside of lockstep with the the Twitter zeitgeist.Just because you can, it does not mean you have to.
That generally tells me he is not really interested in anything, except winning an argument and failing an outright win, adopts his chippy passive persona. My own view of life, is more complicated and in the case of the BBC it flips flops constantly, because I can see the benefits of a public broadcaster.
The BBC itself is changing, but not for the better and its pursuit of the international has saw it neglect the proles in the regions to the extent this debate is so acrid.
