This has been happening for some time now here in the States. The purging is carried out by do-good lefties, who apparently don't want present and future generations to know what life was like in the bad old days (it IS, after all, upsetting, and we can't have that). Thousands of volumes have vanished from libraries, particularly in the South, and naturally there are many African-Americans who aren't thrilled about having their history cleaned up for them. It seems ironic that the more "sensitive" we become the more race-obsessed we are. The first thing we're asked on almost any form we have to fill out is whether we're Hispanic, and then we get to choose from a separate menu of race options (for some reason these are almost invariably set apart). I almost always voice my objection. Heck, it shouldn't matter! Poor Martin Luther King; he just wanted people to be treated equally, not categorized for ease of- well, categorization.
