Sorry Gavra
the burden of proof is on you
There is no Hashkafic evidence that embracing a foreign culture is a good thing, all statements of chazal say the opposite. Feel free to bring some proof.
Yaft elokim is an interesting statement that does require explanation. But the explanation is always a narrow interpretation such as language.
Another narrow interpretation (believe its the rambam, but could be mistaken)is that it simply means that greek philosophy was a better alternative for the goyim than what they had previously (avodah zora).
