The thing is, if they still stock books by actual demonstrable bigots from throughout history (and I'm assuming they must, because the list of squeaky clean authors isn't going to be very long, especially if you go back more than 50 years) then I can't see the refusal to stock JK Rowling books as anything but bandwagon virtue signalling and a bit of free publicity grabbing. Which is a bit cynical and offensive in itself, in many ways.
