In English, miraculously second-person pronouns are gender neutral. The pronoun we use is "you," for both singular and plural. It is thus impossible to misgender a person by "addressing" them with the wrong pronoun. I have had conversations with people for a long time and never had to commit to what gender they are by my use of pronouns. I suppose "you guys" is a vernacular plural pronoun gendered masculine, but you can avoid that one if you want.
In Spanish class, I use "tú," which is also gender neutral. Amazing! The gender enters into "vosotros/vosotras" but we tend to use ustedes. Usted comes from "vuestra merced" and thus was originally feminine in gender, but used to address men as well.
There, right wing and left wing people, I have solved your imaginary pronoun problems. Just address everyone as "you."
Astoundingly, the first person is also gender neutral in English and Spanish. So the pronouns I use for myself at home are I / me / mine. I bet that is true for you as well.
You literally cannot address someone in the third person. By doing so, you are converting the third person pronoun into a second person pronoun. If I said "how is she doing today?" and referring to you, you would be confused.
