Thank you for this book review plus a well put criticism of National Trust recent policy .The Trust tends to pander to the latest trend of emphasizing any connection with West Indian slaves with a 21st century "Tut Tut" viewpoint ignoring Weston societys moral compass hundreds of years on in the past. Roman and PreRoman all the way to Nazi and modern day human Slavery was and is Wrong goes without saying but also if the NT objectively gave as much information of Britain's unique and expensive fight against such a barbaric practice worldwide what a more balanced perspective would be achieved.
The Spanish did more slaving than Britain , and the Catholics themselves ' invented and sanctified ' Atlantic slaving ' ; en.wikipedia.org/wiki/Treaty_of_Tordesillas
