This letter, about the Salaita case, is very good stuff from the AHA. Over on facebook (spit when you say it), Steve Kantrowitz highlighted this passage in particular:

“The First Amendment protects speech, both civil and uncivil. It does so for good reason. The United States made a wager that democracy can flourish only with a robustly open public sphere where conflicting opinions can vigorously engage one another. Such a public sphere rests on the recognition that speech on matters of public concern is often emotional and that it employs a variety of idioms and styles. Hence American law protects not only polite discourse but also vulgarity, not only sweet rationality but also impassioned denunciation.”

And of course the boundaries of academic freedom should be more rather than less capacious than those laid out by the First Amendment.
