Foyle's War features LGBTQ+ characters in storylines that highlight the severe prejudice and legal dangers of post-WWII Britain. While characters face tragic outcomes like blackmail, murder, or arrest, the series consistently frames these as external societal injustices, maintaining an empathetic stance and affirming the dignity of queer lives despite the era's challenges.

Foyle's War features a trans woman character, James, in the episode 'The Eternity Ring.' She is portrayed with dignity, intelligence, and agency. The show's main characters treat her respectfully, and any prejudice she encounters is framed as an external societal issue, leading to a net positive portrayal.

The series consistently portrays Christian morality and institutions with respect, often using them as a moral compass against the backdrop of war. While individual Christian characters may be flawed, the narrative condemns their hypocrisy rather than the faith itself, frequently highlighting the positive role of faith in providing guidance and community.

The show portrays Judaism and Jewish characters with profound sympathy and respect, particularly in the context of wartime persecution and antisemitism. The narrative unequivocally condemns bigotry against Jewish people, positioning the audience to empathize with their struggles and resilience.
