You say he's a professional driver and yet his actions today were totally unprofessional.
If, as they claimed, that Spanish pr1ck was faster than Massa then why didn't he over take Massa? Simple, he couldn't and if he had tried there was every chance they'd collide (as Red Bull did recently) which would have changed the result of the race. Equally in their squabbling they could have lost ground and allowed Vettel through and on to take a better place for Red Bull. So you see Robin it is quite simple, by doing what they did they fraudulently rigged the outcome of the race which can only be described as cheating and should be punished to the fullest extant.
This is bigger than just this race. If Alonso gains enough points (through this and possibly other cheating events) then he could prevent another (proper) driver from legitimately winning the World Championship. I sincerely hope another team and/or driver speaks out about this.
I understand your admiration for his team spirit however like it or not he was part of a race rigging which ultimately could affect the result of the World Championship.
