A former professor at Marquette University says he was fired for exercising his constitutionally-guaranteed freedom of speech.  The Wisconsin Supreme Court is being asked to decide whether Professor John McAdams was fired for a blog post or for his conduct on the job.  McAdams criticized a Marquette instructor for what he described as shutting down a negative discussion against gay marriage.  The school says McAdams was terminated for publicizing the instructor’s personal information so he would be subjected to harassment.
