I do not agree, simple because I perfectly understand modern Croatian. maybe we had similar languages 300 years ago, but now they are same with minor differences.
Don't get me wrong, i do not deny your language or anything. I just try to see thing with non-biased eyes and keep things straight.
Macedonian and Slovenian are similar to Serbian and Croatian though.

@ MegaArgus01 I am not interested in your petty idiocy and provocations.

When no reasonable answer walking away is the alternative.

In my opinion the Slavic language was the same by all, during the time because of the geographic distances and external influences they started to diverge and now with the global communication the differences are getting less.
