Why should Kazakhstan compete in some Asiavision when its culturally, socially and politically part of the "Russian" family rather than any Asian? And oh it already competes as part of Europe when it comes to different sport events, just like Israel does....
I do however agree that Eurovision should not make any further non-European expansions, but considering the things I already mentioned about Kazakhstans relations to Europe (the East Slavic parts atleast) and that it has a part in continental Europe aswell, I just find it hypocrisy excluding them because of some pro-Western European biasism. The Iron Curtain is gone, Europe doesn't end with Germany you know.
