::::1. Croats had, according to the DAI, been a fighting folk who subdued Avars, repelled Franks and saved Serbs from Bulgarian captivity 

2. Serbs were a docile folk who, essentially, didn't fight "their place under the sun". Their very name signified servitude of a sort, as evidenced by the DAI's etymology. They lost every battle  with foreigners they ever fought, placed themselves under Byzantine suzerainty amd were saved from extinction by Croats who crushed Bulgarian aggression

3. there are historical documents galore, which testify about Croatian legal, parliamentary and cultural continuity: from the times of Trpimir and Krešimir to the later corpora.

4. Croatian language heritage in the vernacular is well attested in from the 13th century on (at least). They Croatian name is explicitly mentioned in various sources, both Čakavian and Štokavian, particularly in Dalmatia, Dubrovnik and Bosnia. Moreover, linguistic characteristics are the same as with contemporary (mid-19th century) Croatian language. On the other hand, Serbian written works, up until Dositej and Vuk (1780-1820), were written exclusively in Church Slavic language. Serbian literature until Vuk is, essentially, a variant of Church Slavic literature flourishing in Byzantium influenced area. Hence-Vuk's linguistic pan-Serbism, which tried to appropriate all štokavian vernacular literature is, evidently, a falsity and concoction.

5. early Slavic studies (Šarařik et al.) were deluded in ascribing parts of the Croatian literature to the Serbian heritage.

6. Serbian ethnic affiliation, in modern terms, is a relatively new phenomenon in Croatia. The major part of Eastern Orthodox inhabitants of Croatia, who actively participated in the Croatian cultural life (Illyrian movemont) have begun to show Serbian national allegiance only in recent (1850s) years. 

Virtually all Starčević's claims are corroborated by historical sources available at his times. Whether the veracity of historical sources like the DAI can withstand the test of time-this is another question. But, from the vantage point of mid-19th century clash of Serbian and Croatian ideologies, Starčević polemic stands as an example of skilled, sometimes sardonic and always truthful debate-without distortions, lies or misappropriations. Sarcasm hurts-but, this is what the polemic is all about.
