I fully understand that, but allow me two points:
FIRST: your statement that it “was his own fault for hitting it in the water” is remarkable in its lack of understanding of what happened. He did not flub a shot into the water. He hit a shot that was almost accurate beyond what golf pin equipment is designed to take, and it bounced hard off the pin back into the water.
SECOND: given that he did not “flub” a shot, and by virture, should have had a 4 on the hole and not an 8 - except for the bad luck = it was a NET 4 stroke penalty while yes, it was only a GROSS 2 stroke penalty. You either didn’t see the shot or don’t understand the game - or both. If you did, my connotation would have been obvious.
I’m getting a little sick of your condescension toward anyone who disagrees with you.
We agree that it was an unlucky bounce, but the fact remains the ball went into the water. The consequences of that situation apply equally to everyone, and shouldn’t be viewed as part of the punishment for the separate rules violation.
