I agree. I recognize that gender & gender identity are important topics, and I don't mean to make jokes of it.... but these implementations are horrendously bad. Who builds an input form that says "Gender: Male, Female, or Hot Bread" and thinks "yep, this makes sense!"

Much like the others, this is most likely a ui reading the options from a dataset that was contaminated somehow. Combined with lack of maintainers actually using or testing the thing they maintain on a regular basis.
