Idk about Albanians, I haven't been there, but all of people of Yugoslavia are super friendly. As for Croatia, I went on vacation multiple times and we have cousins living there(they're not from Croatia, just living there) and I also have friends from Zagreb and Tito himself was half-Croat. It's just that the situation is same as in other countries in Yugoslavia, i.e. rehabilitation of nazi collaborators ustashe, same as chetniks in Serbia, church, reactionary westoid puppet government etc etc.

Btw I have heritage from Serbia, Bosnia, Montenegro and Macedonia.
