well, you do seem to hold a belief, that people with dishwashers must pre and postwash dishes by hand.

You could consider placing this belief in the open for people with dishwashers to contradict a sort of test, but you don't appear to consider it that way. Do you still think that everyone in this thread with a dishwasher washes their dishes by hand before and after they put them in the dishwasher?

You're accusing people who use dishwashers of a profoundly inefficient process. I think that you don't recognize this as insulting, but I also think that you derive a sense of superiority from this accusation, and if you are holding onto this belief in spite of people's insistent contradiction, then I think that this amounts to superstition and vitriol on your part.
