Welcome to HN as a commentator!
Where is "ultra-nationalism" in my two comments here? Or which "random facts'"? I quote English Wikipedia and these entries were edited by Croats. That one link with the list of "croatian" rulers is identical to the same entry in croatian Wikipedia.
OP was "pedantic" and has claimed something that was plain wrong. And using his logic, I was pedantic as well - to set the record straight and provide background info. The alternative is to let Croats claim whatever you want while betting on ignorance and lack of knowledge of others.
