So I’d understand why the asari wouldn’t have gendered anything on their own, but you think that once they saw other races, at least some would choose to present as male. Every asari in the three games is presented as female, and I think it shows a super simple understanding of gender and lack of imagination.
It’s really kinda boring that every asari would choose to be female, especially since I’m sure each individual has their own preferences and attractions. I’m realizing how shallow Mass Effect’s politics are, and how much broader their world could have been, instead of reducing each alien race into Roman wannabes, sexy blue ladies, and the lizard proletariat.
TLDR: No male asari feels like trans erasure.
Even the jump between ME2's intro and the start of the game proper feels weird. Like over the course of two years Garrus not only founds a vigilante organisation but then promptly loses them all in a siege, for example.
