Not appropriate to play the race card in a discussion of TC, never mind boiling the many drama's that followed MS down to a single "Adelaide" incident which is disingenuous at best.
Face it, being German seems to only bother other Germans, the rest of the world are trying to figure out how to copy Seb's advantage and level the playing field, which will be good for the sport.
So... you can't possibly argue with the message, and that is why are you now trying to discredit me? It is a very old trick and i've seen it plenty everywhere... perhaps that may not be your intent so i will try and answer...
People have their preferences... to deny it, is to deny human nature. Everybody has bias built in them, some more than others (and i claim to be no exception). Motor racing started as most other sports, with competition between nations... Even after modern GP era began in 50's there were clear lines about who was from where, and you can't argue that. Not unless you want to rewrite history... There's one more thing... while we're at this. If either drove for a "proper" British team (Williams and McLaren, as people seemingly don't realise most teams are based in UK anyways ), they both wouldn't have gotten half as much crap as they did and still do. Like it or lump it, most of the F1 media is British, and as much as media may love them, it is possibly beyond any question that British media would have loved them more if they drove anything "proper" British. Look no further than Senna... he was a jerk (to put it mildly) on track, but media revered him and still does... Look no further than Prost who spoke against the very same team, and media doesn't hold him in much regard.
About Adelaide... i was drawing parallels from early part of their (Schumacher and Vettel) respective careers. While his team may have had been involved in many dramas as you put it, but can you point to other incidents where you could hold him guilty (for lack of a better expression...)
