The point was that it was not modernising. Would a random central asian country adopting the latin alphabet be making progress in your view?
No. Of course Ataturk did more than just changing the alphabet.
I'm too lazy to type about Ataturk but check my post here. It was from a loooong time ago but pretty much sums up what I think of him.
Furthermore if you try to enforce secularism it most probably will not work. Religion dies out with cultural changes, not because someone declared it dead.
Especially if he did not have an impressive mustache
Relgion do not die out. Religion will survive even in the most secular states or it will just changes into another form or mixes with other religions with time. Secularism does not = atheism. Atheism cannot be successfully enforce for it abolish religion altogether. Secularism can be to some extent.
