There was a report in the British press about a WWII re-enactment event and a group of about 8 chaps arrived in German Army uniforms. To my astonishment, apparently this caused offence in some quarters. I don't know when people became so over sensitive and ready to be offended by anything. I heard a recording of a speech in the 1960s by the famous RAF flying ace, the double amputee Douglas Bader, at some Battle of Britain Association,. They had invited the famous German ace Adolf Galland, who became friends with Bader when the former was shot down and captured by the Germans losing his prosthetic legs in the process. Galland organised a safe corridor so that the RAF could air drop another pair for Bader. Someone had asked Bader how he had the temerity to invite a previous enemy and he replied "If it wasn't for chaps like him there wouldn't be a bloody Battle of Britain association!"
