Is the Wake County school board's proposed ban on personal attacks from speakers too vague?

As noted in today's article, Katy Parker, the legal director of the ACLU of North Carolina, says the policy being voted on today leaves too much room for interpretation as to what would be considered a personal attack. She said what one person might consider a personal attack might not be viewed that way by another person.

In this case, school board chairman Ron Margiotta would be the person making the call.

UPDATE

The N.C. Open Government Coalition is also objecting to the speaker policy. Go to the end of the post to read their letter.
