It is your opinion. You have explained to me how you feel certain actions by players should be treated. I have disagreed.
You believe that preparing an ambush is a reportable offense based on your own concept of what is honorable. I do not. It is simply another way to catch an opponent and eliminate them in order to win. Unfortunately, there isn't much more I can say about this. It seems completely reasonable to me so I reason that any differences we have on this matter stem from a misunderstanding in how "bush-camping" is defined as you never provided a succinct definition (despite my asking).
You believe that emote-spamming is report worthy. I do not. I believe it is a generally harmless, albeit annoying, action that does not significantly impact the game experience. Of course how this affects each person that experiences it is different. That is why I will only do it in the presence of those, such as my brother, that I know do not mind. Because I am unsure of how others will react, I refrain from doing it because it is an action I find unnecessary to my own enjoyment of the game. However, should another person enjoy spamming emotes, whether to taunt or bait their opponent or simply to enjoy the nonsensical quotes and movements of their champion, it does not overly bother me and I have no problem with allowing it. That is why I would not report it.
That said, I will not tolerate anything abusive. Should another player show severe discomfort (beyond simple annoyance or anger) and ask the offending player to stop, only to be met with continued spamming, then I would believe the offending player had caused unnecessary distress and I would strongly consider reporting them.
However, what I believe to be unnecessary distress depends on my moral relativity. As I explained previously, frustration, anger, disappointment, pessimism, and other negative feelings which may be considered distressing are all to be expected in a competitive game. I believe that emote spamming is just another facet of the experience and is, for the most part, harmless in that regard.
However, my beliefs differ depending on the offending action. To help explain my stance I present the following scenario:
Many players will complain and become extraordinarily irate if someone were, for example, to continually gank their lane, especially with Champions such as Shaco, Evelynn, Vi, Warwick, etc... that are notoriously difficult to defend against. Despite causing the player distress, those ganks are beneficial to the gankers' team and their hopes for victory. They put the enemy laner significantly behind. They can anger the enemy laner thus preventing them from thinking rationally. They can use their lead to pressure other lanes. It is an allowable strategy that is supported by the game's objectives and mechanics. I would not condemn this action at all. If one cannot handle being the target of coordinated gameplay, then they should be more hesitant of playing the game. Repeatedly attacking an enemy player that is behind may not be the most honorable thing, but so long as it serves the purpose of helping the team achieve victory as opposed to simply belittling the opponent, I find no issue.
To put it bluntly, I have agreed with the majority of what you have posted elsewhere in the thread (barring a few naive statements and your general attitude in addressing others) so it baffles me that we have such a vicious disagreement here. I have once again attempted to explain my beliefs as clearly as possible to eliminate any potential misunderstandings and hopefully put this unpleasant episode behind us. In the end we may still disagree, but I hope that we can do so without demeaning each other.
I will also state that I am not trying to argue that emote spamming or ambushing opponents is the "right" thing to do, only that they are not "wrong" and not something I would consider report worthy. As you so eloquently said, "no one has the 'right' to be disrespectful." However, what one considers disrespectful is up to our own interpretations. To claim otherwise is to deny reality.
Finally, I assure you that I do not lack empathy. You don't have to worry about that though I appreciate your concern.
