The Ottoman census reflects only the religuious adherence of the population and nothing else

Exactly. So what makes you think that using religion as the primary criterion of nationality is not the closest thing to the truth? Maybe it is, and maybe it isn't, but neither you nor me are in position to decide that. This is why in my version all criteria used in the demographies are explained in detail, without deciding which is right and which is wrong, and that my friend is what we call neutrality. You might as well try and take a hint. Nothing from the Turkish cencus proves nor implies that those Greeks were not Greek speaking. The majority of Bulgarian population had never been adherent to the Patriarch of Constantinople. You're confusing yourself with the small Bulgarian or Slavic-speaking population which viewed itself as part of the Roman nation which had lost its mother tongue over time. Therefore despite religion and language, the greater part of the population of Southern Macedonia viewed itself as Greek (or Roman if you prefer). Then if we can't trust any demography, think of the population exchanges. 50,000 Greeks entered Greek Macedonia from Pirin Macedonia, and some 60,000 Bulgarians left for Bulgaria. Then some 500,000 Greeks enter from Turkey and suddenly, we have some 1 million Greeks in Greek Macedonia? Where did the other half million come from? Mars? Oh, I know, it's a Bulgarian "majority" group that the Greek government is still hiding isn't that so? And now think of the ludicrous numbers that you're trying to pass as the truth: 2 million Bulgars in the entire of Macedonia and the assumption of another million in the south. I mean, use your brain for ones and do the maths - have you ever checked what the population of Bulgaria is today? Honestly some people just can't take the truth. And if neither of that convinces you then think of the Greco-Serbian alliance. Would the Serbs have ever agreed with Greece occupying over half of Macedonia for itself unless that land was not primarily Greek? Serbia was significantly stronger than Greece and in the search of Slavic-speaking lands to assimilate. It would have never happened. If you really want to do something to help your country, I would advise you to go over there and offer your people some physical help. I don't think that making nationalist propaganda of the internet is one of their priorities at the moment.
