Greg Quinlan is the president of PFOX--Parents and Friends of Ex-Gays & Gays (PFOX).  It's a national non-profit organization that supports families, advocates for the ex-gay community, and educates.  Quinlan argues that ex-gays should be considered a 'protected' class against hate crimes.  He also says that persons who are gay can be rehabilitated to become straight--which is derived in large part from his own experience in doing just that.
