Debates in French, Arabic, and English

I don't know, if Ergun speaks Arabic or not.  I have seen evidence that he spent three years in French club.  His Swedish mother studied in Paris, so it is likely that she spoke some French. Outside of this 2002 mention, I have not heard a non-blogger mention that Ergun spoke French.

The heightened interest in Islam has drawn each of the Caner brothers into additional debate settings at mosques and universities, speaking in English, French, and Arabic with Muslim scholars. And they have been interviewed by the BBC, CNN, Moody Broadcasting Network, Salem Radio Network, and USA Radio. Talk show invitations have come from Pat Robertson, Jerry Falwell, Marlon Maddux, and Zola Levitt.
