>>8781956>Leave West Slavic countries outWe have more in common with west slavic countries via genetics and via history (centuries together in austro hungarian block) than we do with serbians though. Just because the language is very similar does not mean we are the same. For example Hungarian and Czech are all in the same cluster as with Croats (and slovenians) while serbs are much much further out and historically few decades of yugoslavia that always fell apart just demonstrate the differences are there.
