Boyer tried wrecking Gordon twice before Gordon stuffed him. Basically what happened to Boyer is what would happen to gasser every single week by every single car she races against if she wasn't a girl. I have no clue why Boyer was soo pissed when you run people like that you should expect them to return the favor and Gordon did
You might want to look at the replays. They bumped a little on the backstretch, then Gordon basically screwed himself when he tried to take Bowyer out going into 3 but crashed himself. It cost Bowyer a 2nd place in the championship. I wouldn't be surprised to see the 56 repay the favor by taking out the 48 next week to get Bowyer back to at least 3rd.
