It was just a general comment (about internet reaction to Rosberg winning) about how many people are trying to devalue someone's life work, just because he beat their favorite driver. The various excuses, some relevant, some not to try and say that Rosberg is an undeserving winner.
It's pathetic really. Especially considering, a similar argument can be made about Hamilton 2008 title or Alonso's 2005 title etc.
Hamilton had championship winning drives in 2008, like Silverstone where he outclassed the entire field by a mile in the wet, showing up seasons professionals for how to cope in wet weather.
Rosberg hasn't had a single 'epic' drive this year, he hasn't had a single epic move. He's had 4 or 5 gifted victories in the fastest car where the other Merc started 10th or below with zero chance to win, and another few wins mostly in tracks where either Hamilton was hit in the first corner or had a bad start.
I don't think he ever 'won' a race by being less than 1st into the first corner(s) and passing someone to take a victory.
People like to make out that Hamilton was gifted the win at the end by Glock in 2008 but the reality is until Glock decided to stay out on dry tires when almost every other driver decided to pit for inters, Hamilton had it won. When people make the entirely wrong call on tires it often bumps them up for a lap or two them causes them to look like idiots, it doesn't matter it was the last lap or not. Hamilton actively won multiple races that year with some brilliant drives, Rosberg can't be said to do the same.
Despite multiple failures, despite having to start at the back for Spa, despite Rosberg hitting him twice he was still leading by was it Germany, then Malaysia happened again giving Rosberg an unassailable lead.
It's got nothing to do with being a Hamilton fan or not. If you take out the races Hamilton had a failure in qualifying, the race or Spa starting from the back to make up for said engine problems, Rosberg got thrashed in race wins and thrashed in qualifying while not putting in a single genuine championship winning drive at any stage of the season. Even considering Hamilton's reliability problems Rosberg still lost on race wins and qualifying.... despite an effect 4/5 race head start.
