I personally don't think they need to be banned Deerouz jaan, but they should not be able to touch a secular constitution once it has been enacted. And please let me clarify that the whole drawing up of the constitution in Iran and Egypt was seriously flawed - the constitution is NOT meant to be a document put to a referendum - it is intended to protect the rights of all the citizens, the minorities being the most important ones and in that sense, a popular vote on a referendum will not achieve what a constitution is intended to achieve.
Once a good secular constitution has been put in place, an Islamist party (if elected) can certainly try to enact new laws within the framework of that constitution. There is nothing wrong with that and that's like any conservative party in the West trying to enact conservative minded statutes. The most important part of the equation is that there be an independent judiciary where any of the new laws can be challenged if they override the constitution, the same way the process would work in the west. I actually don't think the process is working as well as it should in the West either, but at least it's on the right track.
The only other self-correcting mechanism that I would place in the system (currently missing on many levels in the west) is a small committee of 12 non-partisan judges that could actually impeach the PM or president instead of the parliament, based on complaints on violations of the constitution. With those three things in place, the system is pretty fool proof. In Turkey's case, this committee would have been able to simply impeach Erdogan even before the protests broke out on the constitutionality of his restrictions on the media and certainly after the protests broke out on the constitutionality of his actions against freedom of assembly. This type of committee of judges would be very useful in cases of corruption as well, so we wouldn't have to deal with the conservative government in Canada for example, sticking it to us for another two years without any recourse (and we didn't have to deal with the Liberals either about a decade ago).

In a society that has Islamist parties and ... who will have the power to write that constitution ? How will that constitution be written ?
