It wouldn't have been if Jeremy hadn't just had a conversation with it first, and then said it."Lesbians" with deep voices are a growing population these days, it's not an unreasonable mistake to make over a phonecall.
A good compromise just use their name, their chosen name is fine by mewant you to say she/her and believe it's a microaggression not to
