Here is your answer plain and simple, I'll say it again. The hate stems from the fact that lining/flossing/snagging doesnt coincide with the ethics of hook and line fishing, which historically means getting a fish to bite at what is perceived as food (or in some cases a threat) with its mouth. It has nothing to do with morality or elitism. NCD, and perhaps others seem to have gotten lost on that there topic.

+1 to Dan.
