Lol I love the oversimplification and strawmanning and then calling out other people for being inconsistent and using logical fallacies. The funniest thing is that even your original premise is flawed. No Djokodal fans think prime Fed was a mug we just think that his slam wins were easier because he didn't face that tough of competition. I can spin just an anti Fed narrative without nuance and context just as easily:
Fed fans constantly say that players with lower ranking and inferior resumes were stronger competition than the players Djokodal faced who were higher ranked and accomplished more based on eye test. When these players play Fed they are peaky gods any other time they're mediocre. Fed fans constantly fly in the face of results for their favorite eye test. Roddick a 0 time W champ a far better grass player than Murray the 2 time champ ad nauseum. Constantly third and 4th tier players play way above themselves when playing Federer and do pretty much nothing else. James Blake a man who never made a slam semifinal is built up as strong, Nalbandian, Davydenko, Roddick, Hewitt, Ancic, Safin, Ferrero, Phillipousis, Baghdatis, Haas etc. are often claimed to be better than Djokodal when they faced eachother, Federer, Wawrinka, Murray etc. All of this is claimed on the basis that their eyes, eyes that are fans of Federer, tell them that the inferior players who played Federer were nearly always better or equal to the superior players that played Djokodal. And we're the delusional hypocrites. Sure thing buddy.
