Surely it’s more prejudicial to say that only Islamic extremists can commit terrorism if that’s what you’re getting at. The definition of terrorism in almost all jurisdictions includes people committing violence for political purposes or in disputes with the Government and the fact that this guy wants to talk to the French Government via the Iranian ambassador might be a clue (or equally, it could be a red herring) that he’s a terrorist and that’s the main point that’s been made on this thread. If you’re saying he’s not a terrorist because he’s not doing it for religious purposes then you’ve either got an agenda or simply don’t understand the way that terrorism has historically been defined.
