Your own media acknowledges Turkey has a problem with racism...
...among Turkish institutional leaders:
Turkish racism: an unpleasant story"When Gen. İlker Basbuğ, the highest ranking officer in Turkey, defined some citizens as "people who don't really have Turkish blood in their veins," he was revealing just the tip of an ugly iceberg."
...as well as in sport:
Can Turkey kick football racism out of the stadiums?"While European football is trying to prevent racism, Turkey mostly tends to wash its hands of it"
...coming from the Turkish players themselves:
Emre racism scandal sees Turkey forced to air dirty laundry again."'Turkish football player drops 'N-bomb' on the field.'"
But I'm willing to contend that the news media can be biased, so here is a personal account of a black female tourist visiting Istanbul:

I can add more - a lot more - from Greeks, Armenians, Cypriots, Kurds all of whom have experienced state sponsored Turkish violence as recently as the 20th and 21st centuries.
So, you were saying about Poles being racist?
Anyway, you are free to visit Poland but please leave your country's problems with racism back in Turkey. Thanks.
