I don't think he's trolling, but it's a bit more complicated than that.

It was such a success, in fact, that after the war, the Turks sentenced the men who were responsible for it to death.
Let's face the facts here - even the most incorrigible Turkish nationalist will admit that there were massacres, that the deportation of Armenians from eastern Anatolia was a bad move, to put it lightly, and that the whole episode was one of the darkest periods in their history. They will stop at agreeing that the Turks deliberately set out to eliminate the Armenians, which brings us to our next sentence:
Anyone who has studied the history of the Turks and the Kurds would pause at the formulation of this sentence. The Kurds went against the Armenians for their own reasons - there was no love lost between them - and required no prompting from the Turks.
Turks and others who have actually bothered to comb through the morass of vitriol that has been wasted on this subject are hesitant to attribute genocidal intentions to the Young Turks at this time simply because there is absolutely no evidence that they intended to exterminate the Armenians. It is true that hundreds of thousands of Armenians perished during this time, due to massacres and famine, but so did Turks and Kurds who lived in the same region, and in equal proportions. It was a warzone in the frontier between two crumbling empires. I think these facts alone speak volumes.
The term "historic Armenia" is also deliberately (and misleadingly) vague. Historically, Armenia has not been ten times the size of its present day area since the days of Tigran the Great (83-69 CE - that's right, all of 14 years over two millennia ago). If the feverish dreams of the most irrational Armenian irredentist were to be granted, and Armenia extended over 300,000 km, that's a territory the size of the Philippines, and I'd be very surprised if Armenians composed a quarter of the population there before the Holocaust, if even that.
The author himself seems to acknowledge this with his final solution to ethnically cleanse eastern Anatolia of its undesirable (Muslim) elements:
and so on... I probably missed a few but my eyes are bleeding from the small type.
I found this amusing:
Two problems: to start with, the Dashnaks were just one party in a coalition government, albeit the majority. Second of all, the Armenians were undeniably being supplied and supported by the Russians.
I'm not quite sure what this entails. What were they confessing to themselves?
Pleasant for
whom? The Turks or everyone else?
I just can't buy into some of these assumptions. This scenario seems even more dystopian than the OTL, if that's imaginable.
