That´s not necessarily a problem. You might note that in some EU member countries, it is possible to disallow certain political parties. In Germany for example. It is not possible in Germany for a political party to advocate communism or a fascist state. The same could be applied in Turkey. Political projects to undermine the secular nature of the state can be outlawed. And to achieve this the army may be used.
