Seriously?
An espionage mission without any proof of an actual damage is the same for you as commiting pimparoompoo against an entire nation, murdering people left and right (“not even their bones will remain by the morning!”), blighting the entire land for years to come and forcing what little remains of the population into an exile?

I can duel you right now if you want.
There are clashing opinions regarding Gilneas state. Even amongst authors themselves.
Just as the Blood elf quests point at those actions as enough to endanger the whole city and open them to the Scourge and the Amani threats.
And the degree of harm kind of falls short. Mildly less harmful actions aren’t more excusable than the ones that have a bigger impact.
Killing one person or killing ten, is expected to have a response and consequence.
Rogers had the same response as Genn, and in her case she was “just” about a single village.
So you are of the opinion that they shouldn’t start another war and just let those past wrongings go unchecked?
Horde people fight for plenty reasons. Not all survival related.
And even those that aren’t exclusively survival related, might be just as vindicated as the ones that are.
Again, just like Genn is entitled to hate or prosecute the ones that wronged him, there are plenty of Horde segments that are just as entitled as him to feel as such.
Start another war? Sure, why not. Another war was started when Night elves decided to carry out punitive measures against Orgrimmar for what happened at the Wrathgate.
Just as they are justified in doing so, why is it so weird to have the Horde Warchief pulling out a list of past wrongings and going like “Enough, we are making things right once and for all”.
That’s the same logic Genn used in Stormheim.

Ah, I was supposed to deduct that you were actually talking to someone who hadn’t typed a post yet, rather than the person you were replying to, right.
Yeah genius, one can see when people are typing on these new forums. Like, in real time.
Speaking of, I can see Sylvanas pulling a stunt like this in order to get her booty safe. https://youtu.be/6JxObsg6c_Q
Extra: in this analogy the elder gods are either world soul azeroth or the death entity. Kotal is Sylvanas.
Oh no, I am obviously of the opinion that I, as a Draenei, should kneel in front of every orc and ask for forgiveness.
All those past wrongings!
Yeah. Like “Lok’tar Ogar!”.
“Me orc! Me smash!” - is such a just reason 
No, they are not. The Horde invaded Gilneas without any provocation. You are not entitled to any kind of “revenge” against someone you brutally attack for no reason.
Typical Horde 
I need your money because I don’t have enough. You don’t want to give it to me? YOU ARE GUILTY OF ME ATTACKING YOU!
SPOILER ALERT. The only reason Genn is in all of this is because the Horde invaded his land and murdered his people.
Sylvanas was justified, Garrosh ordered it. Remember?
I also remember one Chronicles’ quote about that…
Oh guys, it’s like in the kindergarten with you…
Phhh, Chronicles, Shonicles, amirite? Sylvanas never did anything wrong, the sweet angel, how dare we. I will delete my post in shame.
THEN YOU SHOULD FEEL LIKE HOME! HA! GOT EM!
Sylvanas is perfect, Orcs did nothing wrong. Sylvanas is perfect, Orcs did nothing wrong. Sylvanas is perfect, Orcs did nothing wrong. Sylvanas is perfect, Orcs did nothing wrong. Sylvanas is perfect, Orcs did nothing wrong. Sylvanas is perfect, Orcs did nothing wrong. Sylvanas is perfect, Orcs did nothing wrong.
I also want to add that Sylvanas is perfect and Orcs did nothing wrong.
When someone claims this, HotS Uther is your friend:
“Adding ‘new’ to the Horde’s name, doesn’t absolve you of your sins, you know.” - Uther the Lightbringer
Why should the Horde (or even players), given any kind of validity to his claim, given your stance that dismisses the wrongings Horde people might have, and the motivations derived from them?
Why give a shirt about Genns fee-fees if the invasion of the Echo islands, the sabotages that could’ve opened Silvermoon to another Scourge invasion, the blowing of a neutral cartel ship, or the stuff Lorash complained about, are going to be summarised as?:
I mean, you are free to do so. But don’t act all shocked when the other shoe drops and you have writers taking out the list of Horde grudges and letting another Garrosh or Sylvanas loose.
The motivations are there. How willing you are to acknowledge them, is entirely dependent on your own bias.
Edit:
Given we are to selectively trivialise the wrongs and grudges certain races may have regarding someone else’s actions, I’m going to simply point out that Grom was right in his approach on Draenor:
So…he should’ve definetly genocided their whole race when he could. 
Hope the story gets us to revisit those AU Draenei to finish his righteous quest.
That’s why I like to be here
…is exactly the stuff current elfie leadership did to those who would later become void elves.
Shaw goes they are winning on all fronts, not just at Zandalar which is backed on when Nathanos says “the Alliance are tightening their grip, victory is within their grasp”
That isn’t something to say lightly
