Walter Russell Mead has been blogging a lot on European anti-Semitism recently: see here, here, here, here, here, here, and here (and actually read them; Mead is a voice of deep moral clarity). On one of those posts I left a comment regarding something I experienced last month. I was getting off a train at Brussels-Midi and, while waiting for the train to stop, stood by a door that had the "danger: electricity" sign on it to warn passengers not to open it. Under the sign, someone had scrawled, "Only Jews inside".
I stood there staring at it for about half a minute as it sank in. I was standing on a train in western Europe looking at a casual statement wishing death to Jews. It made me sick to my stomach.
