I haven't suggested that anyone is racist or that the memorial should be changed. There's a lot going on right now that seems pretty pointless but digging your heels in trying to justify the use a term that was at best unpleasant at the time seems a bit daft.
My Dad was definitely a racist but even he never used that term. He did lots of good things for many people too.
I for one am not trying to justify a term, just put it into historical context. If you google the mascot for 617 Sqd during the raid it will say that lots of dogs were called ‘nigger’ back then. Did everyone do that out of hatred. You tell me!
Although why would anyone call to their own pet in anything other than an endearing tone of voice.......unless the pet had just chewed their best slippers!
