The Sitter features an openly gay character, Rodrigo, whose identity is largely reduced to a source of stereotypical humor. His portrayal relies on exaggerated traits for comedic effect, often at his expense, without offering depth or a counter-balance to the mockery.

The film features Roxy, a transsexual woman, whose identity is primarily used as a source of crude humor and discomfort for other characters. Her portrayal leans into harmful stereotypes, presenting her as a sex worker and the subject of demeaning jokes, without offering counterbalancing positive elements or critique. The net impact is negative.
