Original sentence: "Mankind" is a commonly used phrase to refer to all of humanity.(In some cases, such spellings are based on entirely inaccurate etymologies.However, it is considered sexist by some, and hence, is commonly replaced by "humankind" or "humanity".Now that women can have those jobs as well, those terms are often replaced by neutral terms like "firefighter", "police officer" and "mail carrier".Some have proposed alternate spellings for words such as "woman/women" which are perceived as deriving from a masculine term; see womyn.The term herstory has been suggested as a feminist alternative to history; however the notion that the term "history" is related to the masculine pronoun "his" is incorrect.The word was historically used very generally as a suffix in combinations like "fireman", "policeman" and "mailman", because those jobs were historically only jobs that men did
Edited sentence: Mankind is a commonly used phrase to refer to all of humanity, regardless of sex.The word is commonly used very generally as a suffix in combinations like fireman, policeman and mailman, because those jobs were historically only jobs that men did
