This. I have a growing sense of urban ideological terrorism. Certainly, at least, a campaign of "kidnapping" intellectual spaces and holding them "ransom". The only way to deal with this is to not capitulate. Ever. Open formal dialogue - not twitter, or Social Media dialogue, is the only answer. A moderated formal debate can only result in them failing because hysteria, outrage and hyperbole have no place in a reasoned dialogue. If anyone capitulates to them it invests them with moral authority and makes their next ambush more reasonable seeming.
