When people say (specially Afrocentric’s) say that ‘Egyptians we’re black’ aren’t they just referring to the 25th dynasty of Egypt ruled by Nubian Pharaoh’s?

If so then why so much of a debate around the topic , isnt it a historical fact? Or is the pan african claim that all Egyptians throughout history were black, which clearly isn’t true
