It looks like Air BnB inclusion policy is not safe for women. It lists 'gender identity' as a protected characteristic but not sex.

There have been past instances where female guests have been sexually assaulted - even murdered by their hosts. Considering the intimate nature of such a service Air BnB really don't seem to understand or care about women's safety.
