Croats are much closer to Hungarians than to Serbs by Autosomal Genetics, how do you explain it?

Not true friend. Highest percentage of I2a1b is in area of South Croatia, Montenegro and Herzegovina. Up to 60%.

Diversity and percentage are not same lol.

Its a scientific fact that Dacians (just an example) carried I2a1b. Were Dacians slavs lol? Nope

This is not true.

This is not true.

Im pretty sure Dacians had I2a. Not all of them but majority.

The ethnogenesis of Serbs and Croats took different paths; the Croats were more insular, mountainous (except for the Dalmatians, who were originally more Latinized and only after that got Croatized), while the Serbs were more affected by the invasion of the Ottomans. Thus, Vlachs, Romanians, Bulgarians, Kosovars, Montenegrins, took on the Serbian identity, while those Slavs that were influenced by the more high-society Catholic culture took on the Croat identity.

The reality is that Serb vs. Croat dichotomy is dependent more on religious loyalties than most other ethnicities in the world, and this is why "Serbs" developed as an extension of east-Slav culture and Croats as an extension of west-Slav culture. So even though before Christianity these two people may have been a lot less extensive (i.e. mostly located within Bosnia), over the centuries the Serbian ethnicity expanded much further east than the Croatian did west (because what is considered "Croatian" in northwest Croatia is actually west-Slavic (Serbs to this day have little qualms with the Kajkavians, who didn't even participate in the Yugoslav War; why would they, after all, because they are entirely different from rural Catholic Croats that speak Serbo-Croatian)).

So the question is really a tautology; why are Croatians closer to Hungarians? Because they are farther from those that developed as Serbians after centuries of Ottoman hegemony. Hungarians often moved to Croatia as they were given land, and west-Slavs developed the Kajkavian dialect, much different from the standard-Croatian language which is basically Serbo-Croatian. One could say that the "Serbs" and "Croats" were all similar people (i.e. the Illyrian-Thracians) until Christianity split them apart and west-Slavs (more Germanic influenced) influenced the "Croats".

tl;dr: Northwest Croats are the true Croats, and they spread their cultural ethnogenesis east to the "Serbo-Croat" proto-group, during the time it itself spread east to "Thracian" lands after part of that group accepted Orthodoxy. One can even say that the Serbian ethnicity spread as a survival mechanism as the various peoples (in what is today considered Serbian lands) were subjugated by the Hungarians, the Bulgars, and most importantly the Turks.
