Why would you be (apparently) offended at what sounds like just honest difference of opinion here?

An 11x14 (or 11x11 or so square) from a 6x6 FP4+ negative is "grainless for all practical purposes" to my eyes, meaning if I get really close and look really close, without my glasses (I am very near sighted and can see very well if I get very close) I can make out the grain, but otherwise not. Tri-X is a bit more but still invisible unless you look closely for it. I would not hesitate to make a 16x20 from a MF Tri-X negative. Now if I were making 16x20s from 35mm, then maybe the differences between Delta 100 and TMX would be significant even to me.
Even if one can see the difference and prefers TMX, I can't see it being enough to question the film/developer combination. Something else is going on here.
