Who is Pure nation today?

Another argument the Skops tend to use is that Modern Greeks are a mixture of Slavs, Albanians, Turks, Skops etc and the Greeks stopped existing a long time ago.
I am curious to know who was transforming these Slavs, Albanians etc..into Greeks. It wasn`t the British like the Skops claim because they were not sending british people to our schools, Churches, Villages etc to teach them Greek.
Greeks must have existed to continue teaching our religion in Greek, our children in Greek our traditions in Greek.
Greece is dotted with Orthodox Monastaries all over it`s land, and they are dated at all differenet times from a hundred years old to over a thousand years ago.
Hellenism never died. Artifacts do not lie.
