Last week about twenty people were killed in Paris due to a clash of two ideologies: one religious and one of free speech.
Friday morning I boarded a rush hour train to Leiden. I sat down opposite to a young woman with a black headscarf. She telephoned softly while the Metro (a free newspaper) was lying opened in front of her on the small window table. I was curious and turned my head slightly to see if she was reading about the Parisian affair. That was not the case. Then, while continuing calling, she rearranged her newspaper and with small shocks pushed the underlying Metro in my direction.
