Poland must accept Serbian explanation that Turkish expansionism and islamic fanatism endangering Slavic elements on Balkan.
Firstly, We Turks are not fanatic muslims.
Secondly, there is not Turkish expansionism in Balkans but we of course support Turks ( living in Bulgaria, Greece, Macedonia, Kosovo ), Bosniaks, Albanians, Gagavuz ( christain Turks living in Romania ) when they need help.
All the Turks and muslims are in pressure in Balkans. Of course we do our best to support them.
But, the difference from your point of view is ,
This support is defensive not offensive.
On the other hand, I never heard name of the guy you mentioned. But, I can say he is not Turkish. This example does not show Turkish German friendship.
