Pansexual people aren’t pan because they also like trans people, although in the past some people misused the term that way, e.g, “I’m not bi because I’m into trans people, I’m pan.” That is harmful because obviously trans women are women and trans men are men so if you are bi, you like women and men, that already includes trans people.

For sure there is nothing wrong with having sexual preferences. If someone prefers their men without a vagina nbd. But pansexual just means you’re open to being into anyone regardless of gender. I’m pan because I’m into women, men, neither, other… Any expression of gender.
