However, I (an armchair linguist, I should note) am also a big adherent to the Sapir-Whorf Hypothesis: your language affects your world view. And in terms of gender, there's at least research[1] that shows linguistic gender affects our perception of things. Of course, as with all research, it's open to critique, but I don't have the training for evaluating research in this field. Maybe someone else better equipped could chime in.
Interesting quotes:
> In one study, we asked German and Spanish speakers to describe objects having opposite gender assignment in those two languages. The descriptions they gave differed in a way predicted by grammatical gender. For example, when asked to describe a “key” — a word that is masculine in German and feminine in Spanish — the German speakers were more likely to use words like “hard,” “heavy,” “jagged,” “metal,” “serrated,” and “useful,” whereas Spanish speakers were more likely to say “golden,” “intricate,” “little,” “lovely,” “shiny,” and “tiny.” ... This was true even though all testing was done in English, a language without grammatical gender.
> Look at some famous examples of personification in art — the ways in which abstract entities such as death, sin, victory, or time are given human form. How does an artist decide whether death, say, or time should be painted as a man or a woman? It turns out that in 85 percent of such personifications, whether a male or female figure is chosen is predicted by the grammatical gender of the word in the artist's native language.
The second quote struck me in particular because when I first came across this, I just had a vacation in Paris where I visited the Pantheon. In one of the Pantheon's pillars is a depiction of Death (French: La Mort, feminine) and it struck me as very curious that in this depiction, Death is female. The only other work I knew of to do that was Neil Gaiman's Sandman.
(This is already long enough, but going back to the topic of "Latinx" terms...I don't intend my point above as an endorsement of this practice. In fact I find them quite virtue signalling. I have more thoughts on this but I think the majority of gender (and racial) activism is distracted on bike shedding issues such as using this "x-form". But enough said for now.)
