Calling Azerbaijanis Turkish Instead of Turkic

Hello, brothers and sisters, how are you? Today, I will consult you about an issue I have noticed for a long time. First of all, let me clarify that I am an Azerbaijani. As we know, Azerbaijanis and Turkish people are both Turkic peoples and related nations. But, of course, just like every cousin nation, even if we have a similar language, our histories and cultures are different from each other. Turks have lived in the Anatolian region, established states like the Ottoman Empire, and have a more Middle Eastern region-based culture. In contrast, Azerbaijanis have lived in the Caucasus and Iran, established states like Aq/Qaraqoyunlu and Safavid, and have a more Caucasian-based culture. This is quite normal. Norway and Sweden are kin, but we cannot expect them to be the same. However, the problematic point is that Turkish people insist on considering Azerbaijanis as "Turkish." As Azerbaijanis, of course, we are Turkic people, but the word "Turkish" means people from Turkey or refers to the language spoken by the people of Turkey. What is the exact reason for this? Is it related to underestimating Azerbaijanis and seeing them have no their own culture, history, or is it due to not fully understanding the difference between Turkish and Turkic? I mean Turkish is regional idendity of Anatolian Turkic people, calling Azerbaijanis Turkish is like calling Kazakh as Azerbaijani scientifically
