Tofu

I think that food is an unusually powerful tool in revealing things about an individual.

So (now to the title), where did this sort of taboo for tofu all start? "It" can be lumped together with other edibles, such as spinach and anchovies, in the category in which one often states a dislike for, though the flavor of (fill in food here) may have never actually touched taste buds. Associations with tofu are even more fascinating when considering the attachment to lifestyle that it carries. I think the overall tofu attitude is morphing, but some still don't know what to do with it, causing the taboo to continue on. In conclusion, if you haven't tried tofu, go for it. (It sounds scarier than it really is.)
