Many of us learned the game from gentleman, you learned it from watching Caddyshack. Best moment was Rahm & Garcia coming over and giving high fives and hugs to the US team. That's golf.How so? They are cheering for their team, happens in every sport when something helps the home team. NBA player misses a shot on the road? Fans cheer. Opposing QB throws an incomplete pass vs the Seahawks? Fans cheer. Soccer player misses a kick in PATs? Fans cheer.
That's sports. One team being unsuccessful means another is being successful, it's a zero sum game. Fans cheer for their team to succeed, not to be an asshole.
