Question: Ivan Broz stated that a Dalmatian identifiying as a Serb was just as foreign as what two other ethnicities?
Sentence: Their loyalty was first and foremost to Catholic Christendom, but when they professed an ethnic identity, they referred to themselves as "Slovin" and "Illyrian" (a sort of forerunner of Catholic baroque pan-Slavism) and Croat – these 30-odd writers over the span of c. 350 years always saw themselves as Croats first and never as part of a Serbian nation.
Answer in sentence: no
