The short answer is: no! Assuming pronouns without consent risks a lot of harmful impacts for a number of reasons. Some people don’t use pronouns. Other people choose to only share their pronouns with those they’ve gotten to know more closely.
Everyone is different, which is why it’s best practice to wait till you’ve talked to the person about their particular relationship with pronouns.
If someone doesn’t have pronouns listed on their profile, use their name. If you’d like to know their pronouns, ask them directly.
