Not to split hairs---but as far as I know nobody on the forum has suggested that SCA isn't a valid form of fighting.
Maybe they did, but I don't recall it.
No one has. I did not mean to imply anyone here had. The duel did come about based on someone challenging its validity as fighting art. So the context of the whole challenge and my reporting of the events were slanted in that direction of proving or disproving.
An unused weapon is a useless weapon...
