I know you're being a dick on purpose, but Nadal has been continuously requesting a change to the schedule and ranking system for years and years. He has constantly suggested alternatives as well, rather than just having a whinge he's given the ATP options.
He is Vice President of the ATP’s Player Council and Federer is President. They recently had a player's meeting. Clearly for Nadal to come out he must have been frustrated at Federer not leading from the front like the other players want.
However before I blindly support Nadal in what he said,
if he actually doesn't have the support of the majority of players, and particularly Nole and Murray, like he claims, then he was totally out of line in saying what he said.
But if he actually has the support of the majority (or super majority as he described it
) of the men's tour, and Federer isn't listening to everyone else, then Fed isn't doing his job as President of the ATP’s Player Council
