Could be, perhaps you are right. I will never claim to be a Formula 1 expert, so it could be that your explanation goes a long way and should be interpreted as such. The situation was discusses quite lengthy yesterday on Dutch tv (which obviously favor Red Bull) and the main interpretation of the quote there was that Hamilton was sneering at Perez. But they could also have been wrong.
Furthermore I dont really dislike Hamilton. I think he is obviously an excellent driver, a true champions, on of the greats in in the history of the sports. Off court he is (almost always, Silverstone this year still stings for me) respectful towards all his colleagues. Off the court I think he is an example role model in the ways he presents himself towards the media, as a sportsman and from social perspective.
The thing that I find unsymphatic about him is that when he is struggling and has the wind in his face during the race, he has a habit of sneering and looking for excuses as an immediate response. (which he more often than not doesnt repeat or downplays after the race immediately)
