Also, moderating:
I suggest that anyone who hadn’t done so review the guidance here:
Guidelines for posting on transgender issues on the SDMB?
In particular
Do not deliberately misgender another poster – that is, refer to them by a pronoun or other sex-specific term indicating a gender other than the one they identify as. This applies only in cases where a poster’s gender identity is reasonably clear. Likewise, do not deliberately misgender off-board figures. This is a more rigorous standard than we apply in other contexts; we do not normally mod posters for merely insulting off-board figures. Deal with it.
Posts that deny the existence of transmen and transwomen completely violate this standard.
