The Heartbreak Kid includes a minor transsexual character, Martina, whose identity is revealed as a comedic twist. The portrayal leverages the protagonist's discomfort and audience surprise for humor, framing trans identity as a source of shock rather than depicting the character with dignity or complexity. This results in a problematic and negative net impact.

The film presents a nuanced view, condemning the hypocrisy of one character who uses her Christian identity as a facade, while portraying another Christian family as genuinely wholesome and kind. The narrative critiques individual actions rather than the faith itself.

The film portrays the protagonist's Jewish background and family with warmth and as a fundamental part of his identity. While his family can be overbearing, their Jewishness is not critiqued; rather, it provides a cultural and familial context for the character, often with affectionate humor.
