This documentary presented by Ian Hislop BBC2 tonight was real thought provoking stuff. He looked back to the 19th Century then fast forwarded to today's debates on immigration. To be perfectly honest, if you had shut your eyes and just listened he could well have been discussing immigration issues in 2017, but was in fact talking about 1892. Absolutely nothing has changed, even back then there were loads of 'fake news' stories with the press only to happy to whip up anti-immigration sentiment. One of the things that was different being they used to call immigrants 'aliens'. For those interested in the subject it makes for a fascinating watch. Definitely something brexiteers should put on their 'to do' list.
