A software engineering executive in Florida who was fired for listing faith-based preferred pronouns has now filed a lawsuit against his former employer, the Epoch Times reports.

Until recently, Chad Scharf had been working as the vice president of software engineering at the Jacksonville, Florida, location of Bitwarden, a cybersecurity firm based in California. Sometime during his employment, Bitwarden leaders determined that all employees should include their preferred pronouns in their personal profiles on Slack, an online messaging platform, as part of the company’s “inclusivity initiative.”

Scharf initially declined to list any preferred pronouns because the gender ideology undergirding the notion of preferred pronouns violates his religious beliefs.
