Very interesting thread.
I have been a Westerner most of my life, passionately interested in Cowboys and the history of the USA, including the Civil War. Occasionally I will attend a Western weekend when I will dress authenticall, all my dress is reproduction, but with original materials and to old patterns.
For seven years I edited the magazine of the British Westerners Association. One of my editorials concerned the fact that some Texas schools were teaching a "revised" history of the battle of the Alamo so as not to upset Mexicans. Tosh. PC maybe, but children being lied to by adults responsible for their futures is hardly the best way.
I freely admit that many of the members were simply grown ups playing at cowboys, and a lot of them could not even tell you the name of Gene Autry's horse! I suspect there are many re-enactors at military shows who are just "playing soldiers".
Banning SS and Japanese uniforms from shows and revising history will have ad adverse effect. Forgetting the lessons of World War One allowed World War Two to take place. If everyone turns up in British and American uniforms, won't the public wonder who you were fighting, what there dress and equipment looked like, and why were you fighting them? Unless of course you merely want to show how these soldiers lived, in which case you need to get rid of your modern cigarette packets and bottles of Fairy Liquid in your camp.
I am one of those fortunate enough to have never been in actual real combat. I also have a knowledge of the conditions of war from various times, which allows me to explain to anyone asking what it might have been like. All of us have a duty to educate those who don't know. It is not right to deny history, if we do, e will not give anyone the knowledge to deal with the future.
Those of you who would ban "offensive" uniforms, trying to persuade others that those bad people didn't exist may be considered just as bad as those who exhibit those uniforms and deny that Nazi Germany was a bad place, that not all of them were bad.
There are more people in the world now who are too young to remember World War Two than there are those who do. They cannot have known persecution, occupation, abuse and maltreatment at the hands of an enemy. However those, who do must not be allowed to perpetuate their hatred and infuse it into the young.
Are you going to ban Russian uniforms too? For over fifty years they were the enemy, capable of destroying our country in a matter of minutes.
Notwithstanding those people who have suffered as a result of war, the rest of us must be tolerant. We must show history as it truly was, not how we want it to look because it's PC or nice to have it that way.
True, the Germans and Japanese were brutal, but so were the Norsemen and the Romans, and Boidicae was no saint! To allow hatred to colour all our thinking will seep into children and result in future hatred. Just Look at Islamic Jihad, Northern Ireland and the British Defence League.
We must also be tolerant of newcomers and not frown upon jeans and tee shirts. Not everyone can be expected to have a full kit and uniform the moment they join our interest, indeed few can afford it. If we do not allow this we will discourage newcomers and our hobby will die away.
We must not allow history to be repeated.
This is all my humble opinion, and someone fought and died so that I could express it, for which I am eternally thankful. No apologies to Native Americans that I still think of them as Indians.
All this typing is thirsty work so am getting down off this very tall soapbox and having a cup of tea.
