Petition: Dump Men's Chorus interpreter

The Seattle deaf community is abuzz over the ASL interpreter working for the Seattle Men's Chorus. Some complain that Kevin Gallagher he is hard to understand and not certified. The city's weekly newspaper, The Stranger, reports the Chorus plans to keep Gallagher as its interpreter. In an open letter, Chorus executive director Frank Stilwagner says:

I have consulted with individuals who I know to be qualified ASL experts. I have also had conversations with individuals affiliated with the deaf community, including deaf patrons who regularly attend our concerts, to listen to a spectrum of needs and responses, furthering our understanding. While most have praised our dedication as an organization to offering accessible performances with interpreters, this current concern highlights a need to expand those services.

Stilwagner goes on to ask for "constructive feedback." Some have started an online petition here which says Gallagher is not an "effective interpreter" and plan a protest at the choir's show this coming Sunday. Below is a video report from KING-TV (captions available).
