Height has no influence on how I view Pedrosa, and it shouldn't for anyone else for that matter.
It is a fact that most all Moto Gp riders are quite short. I don't believe there is one over 1,80...
Also, like in Motocross (Carmichael, Villopoto, Cairoli and many others are all short. Do people dislike them because of their height? I doubt it. In Formula 1, virtually all drivers are short, kind of like in Moto GP. Do people dislike them because of their height...don't think so.
In conclusion, IMO your question is pointless really...
