Plan B: Use Plan B if you have only a few, larger similarities or differences. After your introduction, in the next paragraph discuss one similarity or difference in BOTH works or characters, and then move on in the next paragraph to the second similarity or difference in both, then the third, and so forth, until you're done. If you are doing both similarities and differences, juggle them on scrap paper so that in each part you put the less important first ("X and Y are both alike in their social positions . ."), followed by the more important ("but X is much more aware of the dangers of his position than is Y"). In this format, the comparing or contrasting goes on in EACH of the middle parts.
So there you have it, a real peace plan that could actually work. Warmongering pacifists want us to act all nice such that countries think we're rational and won't kill everyone with a blind fury, thus making it possible they might actually attack us and draw us into a war. But, if America follows my idea and lashes out at the slightest provocation with unmeasured vengeance, there can be peace. So there's the choice: either be a homicidal maniac thus ensuring peace and love in the world, or be some pacifist hippy while the streets flow with the blood of the innocent.
