On September 29th, we welcomed a high-ranking guest to our meeting: Constanze, former RDK (Rotaract German Committee) chairperson. With the advances of the IS in Iraq and Syria the topic of the evening could not have been more up-to-date. We learned to distinguish between ethno-nationalistic terrorism (e.g. ETA), social-revolutional terrorism (RAF) and religious motivated terrorism (such as Al-Qaida and their advanced brothers from IS).
