Well on a forum, where everyone is an avatar, I usually default to just “he”. I can’t often keep straight who is who unless they have a name like “gamergurl” to remind me. But if I interacted with that person day to day and they looked like a woman, I’d be using the female pronouns. And I am not 100% sure how this person is living right now - with a beard as in some of his pics - or as a woman, as in some of her others (whew that’s confusing). But he… she expressed interest in getting the hormone and going through the process.
As to rejection etc, what was key here is the guy/gal was on the forum for awhile. She is basically like every one else. Actually much cooler as he had a massive truck and the examples of his collection were envious. He basically showed what I learned years ago about gays - they are just like the rest of us in pretty much every way but one. Any fear or rejection based solely on that fact is illogical and ridiculous now that you think about it.
