Actually the further from Serbia you were born the more you dislike Serbs. Croats on the border with Bosnia are more tsundere because they talk similarly and indulge in their music and culture more, they only hate them because of the 90s war. Idk why Pavelić did this to his Orthodox brothers.
A lot of Serb-hating started with Slovenes initially like the line "Srbe na vrbe".
