It's not true that Djokovic has "never done anything like this." He's hit the ball and thrown the racquet in anger often, and even prior in yesterday's match. He barely missed hitting a lines person at RG with his racquet. Are you seriously saying that he should get a warning the few first times he actually hits a person, and then someday get defaulted for it?
In this case, yes. And I would be saying the same for Nadal or anyone else. I don’t think the penalty fit the crime. You could penalize a player a game or even a set, but to just send someone packing from the tournament entirely for a first-time offense strikes me as excessive. Again, I find it funny just how heartlessly you want this rule applied (even though it doesn’t explicitly say that a disqualification is mandatory in this case), yet when it comes to the federal offense (a felony, actually) of entering the United States illegally, you sneer at anyone who says “the law is the law.”
There are 20 million-plus people in the country illegally (committing a felony by doing so) and many are faking Social Security numbers, and yet you say that any enforcement of the laws is inhumane and racist. But then Djokovic accidentally pokes a linesperson and here you are saying “welp, sorry, the rules are the rules.” All of a sudden you’ve become a hardline law-and-order person. What changed in recent days? Oh, I know. You like the fact that this law enforcement sent Djokovic packing. You have a slight agenda in this case, and it shows quite clearly.
As for Djokovic’s past, it is a fair point that he has shown a serious temper on the court, but the ATP should have issued more warnings to him if they were that offended by his conduct. The bottom line is that he had not hit a linesperson before in thousands of matches. In that sense, this had never happened before. I think there should be a penalty for this but instant disqualification is excessive in my view. Giving the opponent a set, warning the player, and fining the player seems sufficient to me for a first-time offense. But I see you have become a big law-and-order person in the last 24 hours, so my pleas are probably falling on deaf ears.
