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.
