after 18 years at the university of sussex, you walked away from your academic post.wonder, having had a few months to reflect on it, whether you are still sure you did the right thing. yes, i'm still sure i did the right thing, because the situation was pretty intolerable for me. at the time, there was this big campaign against me, by who knows how many students, but, at one point, there was over 100 on campus demonstrating against me during a university open day. they were letting off flares, they were writing graffiti, there was posters everywhere with my name on them. some pretty vile abuse. it was intense and very unpleasant, and, you know, not an environment i could do the things i want to do when i teach and research and live a normal life, so it was impossible for me to carry on there. and the union that was supposed to represent lecturers came out basically in favour of the protesters, which meant that some of my colleagues agreed with what was happening to me and that's also pretty difficult to put up with. so i decided to leave. it was your decision. i mean
