The article presents results of a research project concerning trans men’s conceptualizations of masculinity in a mono- and multiracial/ethnic society. Drawing from 60 in-depth interviews carried out in Poland and in the US, the conclusions show that, despite different degrees of racial/ethnic diversity of their societies, the research participants tend to use a similar cognitive mechanism, depicting a model of masculinity represented by the majority group in their country, as the reference point of “just-right” masculinity, and positioning other models as “insufficiently” or “overly” masculine. However, in case of lack of racial/ethnic diversity in a country, it is the neighboring nationalities that serve as the comparative masculinity models. Also, the awareness of the stereotyping behind the schema differs between the two research groups, and while the grouping of masculinities refers to power relations in the US, in Poland it seems to be more related to the idea of compensation.
