Avoid using gender-based expressions
Exactly what the title implies:
- "He fights like a woman"
Implying that "He" is fighting weakly through the usage of simile. However, by comparing weak fighting to "woman", this negatively reinforces and communicates the idea that "women fights weakly".
- "Please feel free to bring your wives along"
The speech maybe exclusionary to people other than husbands, and even wives. Mainly due to the nature of the word "wives" -- it assumes that the crowd are all males and married.
- "Hey dudes/bros"
Though commonly used across all genders, the expressions such as "dudes", "guys", bros" mainly refer specifically to a group of males. In this case, this may cause unintended exclusions to other genders.
