Leo was a foreign invader now? Leo was not a native of the Roman Empire?
The Komnenoi had not become, essentially, "Greek"? (I've read they were originally Armenian, but it was on That Site, I think, so I'd love to see one or the other backed up if someone has the information - no position to make an argument on it, but sources would be good)
Same with the so-called Macedonians. Basil I was definitely an Armenian, but the Armenians were part of the Roman state. The Ottomans weren't.
This would be like the difference between the son of a Mexican immigrant (or grandson or however many generations back) becoming president of the United States, versus Ireland annexing the United States.
To put it this way, the Ottomans were foreign invaders who took over the Roman state and established their new state on its ruins.
To their credit, they took advantage of those ruins to enhance their state and kept the culture around without persecution, as opposed to how the Latins were filthy barbarians who never even tried anything enlightened or even sensible.
Yes, I do support the "better the sultan's turban..." stance. And I'm not Greek or Orthodox.
Just irate at the stupidity of anyone who can take Constantinople and leave it to rot instead of taking advantage of it being a great city. The Ottomans restoring it to its former glory is one of the reasons I'm more-or-less okay (and sometimes pleased) with them despite the irrational part of my brain resenting their conquest
And with that logic the Qing dynasty were not Chinese Emperors.
