This makes me rage and facepalm at the same time. Asari are monogendered so technically it's not lesbian? Come off it! Liara is a woman with blue skin and a funky hairdo. There's nothing remotely monogendered about the Asari.
Mono meaning singular
Gender referring to the Sexual Organs of a given individual
All Asari have the same Sexual Organs, their race is monogendered.
They may all resemble woman, and they all may refer to themselves as woman but that doesn't change the fact that they as a species are all the same gender. Making your point invalid.
