Bill, It sounds like NJ doesn't respect the laws of other states, so that Mass license might not help you out.
As for the original thread, I don't understand why it was locked by a Mod.
If the Mod's comment that gun control was being discussed had to do with one guy stating that he had a gun shipped through an FFL dealer, well, I think that's stretching the word 'discussed'.
I guess I don't understand the heavy handedness here. Lot's of collectors live on the East Coast and might well pass through NJ, and I would think this info would be considered a public service message to those members on this forum.
