Academy Award–winning Crash director Paul Haggis has left the Church of Scientology after 35 years, citing the San Diego branch’s support for Proposition 8 as one of his main reasons.

Haggis explained his departure in a heated letter directed at Tommy Davis, the current national spokesman for Scientology, according to Movieline.  The letter was published on the blog of ex-Scientologist Marty Rathbun.

"The church’s refusal to denounce the actions of these bigots, hypocrites and homophobes is cowardly,” writes Haggis. “I can think of no other word. Silence is consent, Tommy. I refuse to consent.”
