Actually...
Common names of animals often do not reflect their taxonomic status. It's what happens when you name things before you find out how they're related. Thus, saying that there is no taxonomic difference between frogs and toads is sort of true. There are many named 'toads' that are not true toads (belonging to family bufonidae). Just like not all 'bugs' are true bugs (belonging to Hemiptera). Pill bugs, for example, are actually crustaceans.
This seems to me extremely different from saying a domestic cat (Felis catus) is the same thing as a lion (Panthera leo), which are two distinct lineages of a larger family, Felidea. True toads, on the other hand, branch off within the Anurans (frogs), and therefore the term "frog" must either mean nothing scientifically or include the toads. I suppose we could say that toads are specialized frogs. Just like we can say that birds are specialized reptiles. (More specifically, specialized dinosaurs!)
Anyway, stop being such a jerk.
