I guess in your monkey minded world you can just ignore the fact that most late neolithic Europeans were I2 as well and were absolute manlets even by modern south European standards.
Autosomal ancestry is what matters, not Y chromosome. In order to see if some actual causation were there, you'd have to take Dinarics alone and see if for instance I2 bearing Croatians are taller on average than e.g R1a bearing Croatians. That's how you'd work out an association.
