Clearly the writer is venting a little from his perspective. I can empathize somewhat. How often do you watch historical TV shows and view 1970s hair on "actors" portraying 1914 and 1940s folks or they sport incorrectly placed insignia on uniforms etc. I suppose reenactors want to do a bit better than Hollywood. Once you are in the know on a subject, messing up the details can spoil things a bit. However, no point in driving away the people you want to educate either.
What of the folks from across the Pond? Gentlemen of the Sealed Knot have not been mentioned so far. Any comments?
Cheers,
