Here is a simple thing you can include as part of your online profiles: list the pronouns people can use when referring to you. This removes any ambiguity and helps normalize the practice of sharing our pronouns. Not everyone uses pronouns that match the gender they present as and some people use non-gendered pronouns. If only those people shared their pronouns, it would make them feel “other.” That is easily avoidable, though, and why I think it is important for everyone to share their pronouns.
If you are running an event, I’d suggest including pronoun buttons or stickers for people to identify their pronouns. There is a lot of good information in An Organizer’s Guide to Pronoun Buttons. With or without buttons, you can also get in the practice of verbally including your pronouns when you introduce yourself or speak at an event. The idea may sound awkward, but you get used to it pretty quickly.
