Try and be careful on differentiating between debating against someone's opinion and personally attacking them. The former is acceptable, the latter is most definitely not.
I think it was a foolish thing for KP to say, rarely have I seen intimidating an opposition player work. That said, Dare, I have to disagree about you saying that KP can't even compare to Shiv, two very good players, but quite different. As for the bowlers they've faced, well KP has played against 9 of them (I'll give you 8 as Gillespie wasn't on form in Ashes 05). To say that affects his talent is a poor piece of judgement.
KP does talk a lot of balderdash imo, cringe whenever I hear "..and hear our interview with England Batsman Kevin Pietersen".
