Hezbollah and Leftist Academics
Hezbollah will lauch attacks from an area where they are surrounded by potentially apolitical Lebanese. When the Israelis hit back, they hope to radicalize their previously apolitical neighbors.
Similarly, the crackpot academic left will launch rhetorical attacks on Western Civilization. When conservatives strike back at legitimate academic theories that sound a bit odd (Darwin's explanation of evolution is the best example), the crackpots hope to radicalize previously apolitical professors.
Addendum: You can find an example here.
