you have to be able to find out what is a true muslim before asking what you believe…

bahi
sufi
mirzai
wahabi
Alawites
and many other small Muslim groups which have not being recognised world wide
they have different views on there beliefs…
now the koran,does not stand on its own in debate… you have to read the hadith…
and moslems usualy say to non muslims that you have to read arabic to understand the koran(thats like saying you have to read latin to understand the bible)
on islam i would ask a few simple questions like…

the last paragraph of the link…
In matters political Islam is a system of despotism at home and aggression abroad. The Prophet commanded absolute submission to the imâm. In no case was the sword to be raised against him. The rights of non-Moslem subjects are of the vaguest and most limited kind, and a religious war is a sacred duty whenever there is a chance of success against the “Infidel”. Medieval and modern Mohammedan, especially Turkish, persecutions of both Jews and Christians are perhaps the best illustration of this fanatical religious and political spirit.
