Drinking and defending

From Assignment Paris (dir. Robert Parrish, 1952). Sandy Tate (Audrey Totter) is an Eve Arden type, cracking wise and going it alone:

“I may not believe in what you say, but I’ll drink myself to death defending your right to say it.”

The statement spoofed here is usually attributed to Voltaire. Quote Investigator suggests that it is “probably” Evelyn Beatrice Hall’s characterization of Voltaire’s attitude toward another writer. Sandy Tate wouldn’t care one way or the other.
