'Fired' for Free Speech?

Stuart Card, a sometime adjunct instructor of engineering at Syracuse University (NY) , has gained attention from conservative commentators and free speech advocates in recent days over his public account of his separation from the faculty: Card says he’s no longer a Syracuse instructor due to his private objection to how the university handled a recent case of apparent racism involving fraternity members.  Most news reports and blog posts have asserted that Card was fired by Syracuse for privately expressing his support for the fraternity members' freedom of speech. But Syracuse is pushing back on that characterization, saying Card has not taught on the campus since 2015.
