I watched a ton of the Ryder Cup.
The vulgar whooping up the crowd jeers, apparently initiated by some PGA appointed female emcee, was mind boggling, let alone flat out disgraceful.
There's banter, and then there is flat out verbal abuse, etc. that clearly crosses the line. Interestingly, Rory is beloved by many folk here in America (by true golf fans, etc.) as anyone who ever tunes in regularly on the PGA tour events, let alone the Majors, can attest. Obviously, the Ryder Cup, which pitches a team (country) event over the individual sport that it is, along with all of the standard type etiquette, etc. that's commonplace/embedded in the sport, crosses over here. Therefore, a peculiar dynamic shift for sure. However, the vulgarity and such that was on full display at times by numerous individuals, clearly is unacceptable. It's darn right shameful. However, unfortunately, so are we culturally nowadays and for some time now.
I also watched the entire post event ceremonies on the Golf Channel. In regards to Bradley's comments on the injury and both teams getting a half point, I didn't take anything he stated as disrespectful. He actually precursed his sentiment by first stating; 'this is in no disrespect to Viktor.'
The broader interpretation, at least IMO and perspective from what Keegan said is; that this is sport, and if a circumstance should arise, especially one that in theory isn't unheard of and clearly possible, than a different scenerio should play out where nothing is given, so to speak, to anyone. Let the result be decided on the field of play. It's not as if this withdrawal, forfeit, what have you, happened while the actual specific (in the moment) competition was taking place. Even if it did, there still could've been an alternate, substitute, etc. 'waiting in the wings.'
Regardless of the long withstanding rule/agreement in place, margin, etc. at that time of occurence, I'm not sure how anyone, from a pure competition, etc. standpoint can honestly disagree with that.
