It does not take much now days for nations, and individuals to be condemned for the slave trade. Take the example of Wales. Wales is allegedly complicit in aiding slavery because it supplied wool that the slaves used to make clothing! This is detailed in a book by academic Charlotte Hammond Woven Histories of Welsh Wool and Slavery / Hanesion Cysylltiedig Gwlân Cymru a Chaethwasiaeth, published by Common Threads Press. While all that is no doubt true, the textile companies did not benefit from slavery in any sense beyond say, farmers supplying food, did. The raw materials for clothing had to come from somewhere, and it could be argued, that given the existence of slaves, it was better that they had clothing, than none at all, and froze to death, or died of exposure.
It is yet another white guilt claim. As long as we have universities, we wil get this sort of stuff.
