Yes, and I referred you to the page with a more than decent explanation of acoustic resonance, which you chose to ignore. I simply said that instrument makers use the tern in a nebulous esoteric fashion as a marketing or industry term, when describing something. There is an actual definition and while it is something like what instrument makers use, it is more technical and fleshed out.
The way instrument makers use the word is the EXACT context in which it was being debated. Taking the debate outside of that context is "arguing, just to argue".
If almost every respected stringed instrument maker uses the word, then it is acceptable for the laymen to use the word in the same context.
In other words, if Martin and Fender and Gibson aren't moronic for saying it, then "Killed By Deaths" guitar player acquaintance isn't a moron for saying it.
