The show 'Martin' occasionally included LGBTQ+ characters or themes, primarily for comedic effect. These depictions often relied on stereotypes and centered humor around the 'otherness' or discomfort of the main character, rather than portraying LGBTQ+ individuals with dignity or complexity. The net impact is negative due to the use of caricature and lack of affirming representation.

The show includes an episode where the main character, Martin, suspects a woman is transsexual and attempts to expose her, employing transphobic stereotypes for comedic effect. Although the woman is revealed to be cisgender, the narrative relies on harmful tropes and ridicule surrounding trans identity, offering little to no counterbalance or critique of the prejudice displayed.

The show frequently portrays characters as Christian, often depicting church attendance, gospel music, and discussions of faith. While individual characters may exhibit human flaws or comedic hypocrisy, the narrative generally affirms Christian values, community, and moral lessons, positioning faith as a positive influence.
