Apart from some state mouth piece  historians, almost all historians agree on the events happened in Balkans during Ottomani period..

Obviously, there was a christian population there with Serbs/Greeks/Bosnians/Albanians / Bulgarians/Croatians etc , when Ottomans conquered that part.. As we all know, when Ottoman empire was loosing its lands millions of people had to leave the places where they were living and born.

Millions immigrated to Turkey from Balkans (even after 1923, there was a population exchange)..We call them ´muhacirs´. So who were those muhacirs? Insisting that ´ah but they were all Turks´ wont make any sense because we know that there was a mass conversions from Christianity. (We almost all proud of it) We know that some soldiers which went there, stayed there. There were also some Turkmen tribes, some government sponsored ´kolonizator dervisler´- Ottomani islamic missionaries-. But simply those numbers were not enough to create Turkish-Islamic millions there.. Infact, many right wing nationalists in Balkans still insist that  their  Turkish islamic minority are the ones whose great great great parents were subjected to ´forced conversions´. Well of course, the forced conversion is a bit of a cock and bull story but we know that there were serious encouragements for converting people into Islam.. 

Anyway, cutting it short, it was a huge success story as far as how peaceful those masses of people were converted into a religion. Many of them immigrated to Turkey before and after the WWI. (That also explains why we dont look like Turks in central Asia  and why Turkish genes are quite low in people of Turkey today)

But since we dont care about the races and where our families come from, it should not bother us if some of us are having  Chethniks / Croats / Greeks or Bulgarians etc ancestors. Right?

What do you mean by forced? If they were really forced, all the Balkans would be a part of Turkie today.

There must have been some voluntary conversions, nobody denies it. Because Christian subjects of the Empire had to pay more tax and that was why the Empire didn´t push conversions (Why should it, when it´s getting more tax?) but some may have found it adventegous to convert to Islam (Muslim Bosnians, Albanians and Pomaks).

I don´t bother with any genes in my genetic code. I am happy to be a Turk today.

I think you misunderstood (or I was not clear maybe)

Absolutely I agree with what you are saying.. We call ourselves Turk..But it is always good to know that we are all mixed up and such a thing ´pure Turk´ is a bit of a myth. This type of knowledge will make people more tolerant against the other people from other nations as they will realize, there is a great chance that ´their great great great parents were ethnically  Chetnicks or Albanians or Croats or Pomaks or Greeks and by religion. they were Christians´.
