Counterpoint: gendered languages are fucking stupid. A table does not have a gender, why should its word?

The only advantage I've ever heard of is if you're referring to a person, like if there's two teachers, one male and one female, you can say profesor or profesora to indicate which one you're talking about, but that seems like a very small advantage compared to the downsides (always having to say niños y niñas, for example, or remembering whether a hospital is masculine or feminine, or how you should gender loanwords).
