Not sure that analogy quite lands. Words like ‘mama’ are arbitrary—you could change them and nothing real changes. But sexual orientation isn’t just a label, it’s describing consistent patterns in who people are attracted to, and those show up across cultures.

I think it’s more like colour: the boundaries (like where blue becomes green) are kind of made up, but the spectrum itself is real. Same idea here—the labels can vary, but the underlying experience isn’t just invented.
