Just saw a #TDOV post that used "AI art" to depict a fantasy bigender person. I've also seen a lot of posts by non-trans people that center the poster instead of trans people.
You know what helps me feel welcomed and supported when I'm visible? Not so much the vague "I see you!" statements, and not fantasy or stock trans people, but people posting in support of specific trans people in their lives who have chosen to be visible.
