I can't agree. Being Yiddish for 'woe', ('veh') is what one might say when imagining - as a Va/Per smoker, for example - that Captain Black Grape was the only tobacco available. To anyone. Ever. Similarly, a heavy aromatics afficionado might equally disparage a straight dark fired Kentucky.
Disparagement is simply a negative personal, evaluation and therefore understood to be subjective, and it is not at all the same as disapproval, which would be like suggesting that G&H Dark Plug should be reclassified as a Class A drug, or that all those who smoke it are degenerates.
I've been extremely rude about some tobacco blends I've reviewed, but to date no one has, um, disparaged me for it, or accused me of being disapproving. But neither I nor Spearheadbill have been rude about anyone who actually enjoys such a blend. There's no accounting for tastes, as folks say.
In Welsh, we say "Ych a fi" (pronounced 'Ugh a vee', meaning, literally, "Yuck to me"). This I take to be the context of Spearheadbill's expostulation.
