Justice & Development isn't Islamist, they're liberal. They think people should have the right to worship freely rather than have restrictions like bans on headscarves. The "Islamist" label is a smear applied to them by American neocons who don't like their skepticism regarding support of Israel, and by the fascist* opposition party, the CHP, whose ideology is based on nation-worship and military-worship (they're the ones who put the ban on "insulting Turkishness" into the constitution, which the AKP is trying to get rid of).
*Not hyperbole.
I strongly urge you all to change your vote. AKP is one of the best parties here, especially in relation to the other parties in their country.
You know nothing about the AKP.
They aren't Islamist like Osama bin Laden, but they make politics with the religion and promote all to make Islamic Rules to the rules of the state. The most terrible of the AKP isn't their leadership. No their supporters are terrible, they are a mix between religious nutheads and nationalists.
