Most occupational and public office titles date from a time when only men performed these jobs. Contemporary women are involved in all occupations, making sex-labeled titles discriminatory. Occupational titles should describe the job and not the person doing the job. Likewise, the word man is not an adjective. There are only two jobs that are gender specific.
Some phrases exclude females by assuming that allreaders or listeners are male.
Most English agent-nouns which signify the performer of an action have common gender and be used for a person of either sex. The dissatisfaction of many women with this labeling system led eventually to the use of Ms. as the title analogous to Mr . In order to change those thought patterns, the language we speak and think must change. Gender-laden language, as it has been used, demeans the female half of the human race. The English language is changing.
