here are some cold hard facts for those interested:
1. after losing the war in 1994, the az government spent the next nearly 30 years on a) dehumanizing armenians, b) blaming armenians and losing the war for the terrible socioeconomic state of the people in this oil-rich country while president and his family steal all of the money their oil produces, c) pushing armenophobic propaganda on the population since kindergarten age, d) oppressing and humiliating the other ethnic minorities living on its territories, e) regularly violating the ceasefire of 1994 whenever the internal situation get tense and the ppl get angry, f) selectively sending the youths of said ethnic minorities to the bloodiest parts of the frontline whenever said ceasefire violations happen, g) suppressing free speech, arresting journalists, harassing and threatening those who dare to voice their discontent, etc.
2. in early 1920s, josef stalin, in order to appease the new turkish "republic" and its leader ataturk, with the hopes of using turkey as the base for spreading the communist revolution further into asia, passed artsakh (also known as nagorno karabagh) with its 95% ethnic armenian population onto the new created turkic azerbaijan republic (a country that did not exist before 1918, that's what newly created means), despite the opposition from the people of the region in question and the republic of armenia.
3. during the 70 or so years that artsakh was part of the azerbaijan republic as an autonomous region, the gov of azerbaijan did everything they could to a) suppress the development of the region, b) change the demographic of the region by moving turkic population to artsakh
4. in 1980s, the people of artsakh, utilizing their rights stipulated in the soviet constitution, petitioned both moscow and baku to be allowed to reunite with armenia. as a response to this, the azerbaijan government started large-scale repressions against the organizers and activists of the reunification movement. arrests on made up charges, threats and violence followed (more info on all that in the link provided below)
5. the people of artsakh then held a referendum as was their right under soviet constitution, and more than 90% of it's population voted in favor of seceding from the azerbaijan republic. the response to this were the anti-armenian pogroms in baku and sumgait ( https://www.latimes.com/archives/la-xpm-1990-01-18-mn-305-story.html)
6. all this grew into the first artsakh war, which azerbaijan lost, as mentioned in point 1.
to sum it up: artsakh was never a part of the independent azerbaijan republic, during it's brief 70-year forced az control its indigenous armenian people were oppressed via various government policies, the people of artsakh deserve to live a free and happy life in their homeland, free of threats and fear of annihilation that is sure to happen if azerbaijan takes control of the region
to them, it's just a territory and they want that territory without the people.

while you are at it, read up on the armenian genocide and keep in mind that turkey, specifically for this war, moved syrian jihadists to azerbaijan to fight against armenia and artsakh. read up on the kind of internationally banned ammunition azerbaijan has been using against the civilians in artsakh capital, and then maybe make your judgement.
oh, and if anyone tries to frame this as an islam vs christianity thing, send them to hell, regardless of the side they claim to support, bc this isn't it.
