When referring to individuals, do not assume their pronouns otherwise specified by them. Be sure of the individuals preferred pronouns before using them. Or simply refer to them using their exact name:
Such as follows:
Have you seen his performance last night? vs. Have you seen xyr performance last night?
- It's best not to assume one's gender without any prior knowledge. In this case, the individual maybe referred as "xe/xem/xyr" instead of "he/him", which may often result in an unintended misunderstanding or offense between the individuals
Have you seen his performance last night? vs. Have you seen Jone's performance last night?
- Unless specified by "Jones" that the pronoun "He/His" is what he would like to use, we should use the individuals name("Jones") to avoid unintended discrimination by the assumption of gender
Much like pronouns, titles are often misused too:
"Mrs" vs "Ms"
When unsure of ones martial status, "Ms" are commonly used out of politeness to avoid unintended offenses to an individual.
