Balanced use of he and she

I react to insistence on equal use of he and she by turning out sentences such as: "A woman may divorce his husband if she is unfaithful to him."

judges are always "she" and criminal defendants are always "he"

Off topic. We had a good laugh at work today when someone addressed an email to "Dear managers and friends".

How is it handled in other languages with obligatory personal pronouns (German, Romance)?

French has "on," English literal equivalent "anyone or someone," used also as "we" or modest "I."

"On va?" -= are we going? shall we go?

"On peut faire...." = we can do, you can do, anyone can do

very hard to translate, but useful.

I'm sure some native speaker of French will elucidate more fully.

oh yeah, forgot about that. German has 'man' then, similar to 'on', but maybe more formal and way less used.

I notice that he/she balance thing a lot when I read articles on psychology and child development.
