Pepperoni pizza: The really self-righteous dubs do refuse to eat pepperoni pizza. Most of the witnesses I know eat it. When I was in my really self-righteous phase, I wouldn't eat it unless I knew for sure what the ingredients were. This was not that big of a hardship because I don't even like Pepperoni. It was one of those sacrifices that made me look good but didn't really hurt!
Most people here like it, and so they just ask their favorite pizza places to give them a list of ingredients. I started looking into the ingredients of all the brands of pepperoni for sale up here (again, back in the self-righteous phase) because my husband and son liked Pepperoni. I could not find one brand of Pepperoni that actually listed by-products on the ingredients. So I figured it was all another case of "much JW ado about nothing". After that, I didn't bother checking anymore.
