It isn't hate, its just facts. Vettel is class, nobody even his biggest doubters can deny that and he delivers on the potential of his car regularly. But if you truly believe he is 4 time WDC on talent alone you are wrong.
Great drivers are nothing without a winning car underneath them, let's not talk like Vettel is hauling a shitbox to titles here. On average across each season I think you can argue the Red Bull has been the best car since 2010, close at times, dominant at times but never really left for dead lower than say 6th has it? Mark Webber has continually underperformed or had technical issues since basically Korea 2010 with a handful of great performances.
Schumacher in his dominant years also had the best car, what was remarkable (and this applies to Vettel) is he just crushed the rest so consistently it becomes incapable of dismissing their achievements as "best car". If Vettel truly wants every F1 fan in the world to proclaim him as the best driver on talent alone he needs to either a) take on a world class teammate (not happening yet), b) move to a new team and not have a dominant car anymore. The Red Bull team for whatever reason is just operating on a different level to rest and I fear it will remain that way until they get bored or the masterminds behind it get taken away from them (ie Newey), they are like Barcelona in their prime right now and just have that perfect blend to succeed.
In my opinion (and I say this as a known Hamilton fan) Formula 1 in its current format does not lend itself well to a driver like Hamilton. If I had to choose a driver to win my races right now it would be between Vettel or Alonso.......possibly Raikkonen when he's motivated (ie paid).
