Apparently some historians got so tired of keeping track of all the individual Ottoman genocides, massacres and pogroms that they've lumped them all together into the Late Ottoman genocides. To be fair though, that umbrella also includes plenty of Muslim populations getting much the same treatment in the Christian countries created as the Ottoman Empire contracted.
Pfft, Turkiye are rank amateurs compared to Western Europe. They barely even genocided outside their borders.
Western Europeans have committed genocide across every continent and may have killed ~90% in two of them. The land and resources we stole from the victims of our genocides is the foundation stone of all western power to the present.
TBF, the 90% of indigenous people in the Americas died due to disease. Some cases like those infamous smallpox blankets were on purpose, yes, but the vast majority was not. Can't blame the westerners for not knowing how immune systems work in the 1500s.
Not that they weren't genocidal maniacs with the 10% that remained of course.
