right wing politics promotes rigid gender norms
including that only men should be muscular
so muscular women are masculine
and men attracted to a masculine person are gay
nevermind that these are the same people who want to rigidly define women by their gametes, chromosomes, or other biological characteristics (not how buff they are, or how masculine they present)
or that these are the same people who came up with the idea that everyone is straight to begin with ("gay" being a sinful behavior, nobody being born gay)
