Would you Report a person for....

Right at the start of a game a player on my team said " KABR/all Allahu A" For reference (took this from CNN website) "A witness tells Radio France that attackers inside the Bataclan concert hall entered firing rifles and shouting "Allah akbar" So I immediately stopped playing. I did not feed, I did not leave the game. I just refused to play and then reported the person afterward? I refused to play with anyone who would make light of terrorist attacks or as using LOL as a way of subtly supporting terrorists. Heck maybe this person is trying to find recruits. Who knows. I only know it was in extremely bad taste What are your thoughts? What would you have done?
