Fair point but that would be very rare, and indeed you don't need to use the term actress/female actor there, you could just use female.
So, there is a simple and precise word which immediately indicated all the features of the individual which are appropriate in this circumstance. Why force people to use a more complex construction to provide exactly the same information? This is one of the sillier outcomes in recent times of
perceived "political correctness" influencing the way in which people use language.
Are you (and those you are siding with) saying that a language such as French or German (which uses cases - called "genders" - which classifies nouns and adjectives as "masculine" or "feminine" because they reflect the sex of the individual to whom they refer) is anachronistic and sexist?
In French, a male actor is either
acteur or
comedien and a female actor is either
actrice or
comedienne.
