Europe has chosen to define itself as an open society. This allows for individual freedom. But it also gives enemies the opportunity to destroy open spaces, guaranteed by the state, intentionally and with the aim of causing maximum harm. However, it is not only terrorists who are putting the European model at risk.
And, last but not least, the virtues of a free and liberal democratic society must be accepted – irrespective of religious or political creed, colour or race. On the other hand: cultural and social specificity and diversity must be respected.
