Interesting 'read', sad as it is, hope they'll be able to resolve this peacefully.

As for a 'director' being expected to know ASL, in a way, I disagree, a director can use the services of an interpreter to get their messages across...the bottom line is the ability to be able to 'communicate'...whether an interpreter follows the director around daily or the director being proficient to communicate using sign language.
