Just in the interest of accuracy, after making the statement: "I hardly think there is any malice in this at all given both guys have huge grins on their faces." you cited an article about the incident titled "Usain Bolt unhappy about DeGrasse." It doesn't take a lot of cognitive ability to see that there is an inconsistency there.
If you want to distract from that by quibbling over whether Bolt's unhappiness about DeGrasse was based on his feeling that DeGrasse was being disrespectful, there's this:
It doesn't take a lot of cognitive ability to recognize that Bolt's becoming sincerely offended that a competitor would be so disrespectful as to dare try to finish ahead of him in a semi-final race shows a lack of respect on Bolt's part, as did beating on his chest well before the end of the 2008 Olympic 100m race.
See, if I were you, I'd adopt the energy saving strategy (that was the actual issue that led to the finger pointing between DeGrasse and Bolt) and shut it down.
'cause you just keep getting wronger, mate.
