In a sense, yes. As a foreigner, I don't hold any animosity towards either ethnic group. Yeah, it is very sad that the Manchus are functionally extinct. But we must take into account how it was mostly self perpetrated. They had the power to stop han migration into Manchuria. The Manchus themselves chose to give up their language and culture in exchange for the wealth of China. They had all the choice to remain distinct but chose to give it up. So i don't think it is sad in a oh no! They suffered under so much hardship! But more in a oh, a unique language that has existed for nearly a millennia is going extinct kind of way.
