A subtype of the red herring, this fallacy includes any lame attempt to "prove" an argument by overstating, exaggerating, or over-simplifying the arguments of the opposing side. Such an approach is building a straw man argument. The name comes from the idea of a boxer or fighter who meticulously fashions a false opponent out of straw, like a scarecrow, and then easily knocks it over in the ring before his admiring audience. His "victory" is a hollow mockery, of course, because the straw-stuffed opponent is incapable of fighting back. When a writer makes a cartoon-like caricature of the opposing argument, ignoring the real or subtle points of contention, and then proceeds to knock down each "fake" point one-by-one, he has created a straw man argument.
For instance, one speaker might be engaged in a debate concerning welfare. The opponent argues, "Tennessee should increase funding to unemployed single mothers during the first year after childbirth because they need sufficient money to provide medical care for their newborn children." The second speaker retorts, "My opponent believes that some parasites who don't work should get a free ride from the tax money of hard-working honest citizens. I'll show you why he's wrong . . ." In this example, the second speaker is engaging in a straw man strategy, distorting the opposition's statement about medical care for newborn children into an oversimplified form so he can more easily appear to "win." However, the second speaker is only defeating a dummy-argument rather than honestly engaging in the real nuances of the debate.
