I understand that, and I honestly don't find it offensive.
I just find it annoying that the "JDM" term being used makes no sense whatsoever.
JDM is short for Japanese Domestic Market, referring to motor vehicle 3rd party components.
It was suddenly used (started on these forums I believe) to describe cramming of fish in tanks in Japan!
You say Japanese fish salesmen (LFS?) known for heavily overstocked tanks, but that is an LFS problem worldwide, not just Japan.
Yes now the term refers to how we utilize small spaces here, and indeed is not offensive, but yes we get annoyed as peoplemthat are not in the know automatically think it means us Japanese fish keepers cram our tanks like crazy when they see a (often cruelly) overstocked tank labeled as "JDM".
So no offense taken iHonesty, my beef is when certain members state their unfounded "experience" of Japanese people as a race overstocking fish! (see posts a few above)
