@valleyforge It's all the same thing. Movements trying to remake society by forgetting/rewriting the past lead to dark ages.
"Food comes from a grocery store." Not many kids even know steaks come from steers and heifers already in the US. It's going to be a problem when enough collective knowledge is lost. We're practically living in a new Inquisition period (it lasted a long time: 1478-1834) already.
Culture is learned, and people can lie about the past.
