Here are some observations:

In French, she=elle, he=il, and they does not have a direct equivalent. "they" is genderless in English. In French, it is:

- ils, if at least one person in a group is a male
- elles, if everybody in a group is a female.

In other words, there is more importance to being a male - if you are referring to a group of people, it is enough for only one person in that group of people to be a male to warrant the "male they". So the male gender sort of "trumps".
