SURVEY: ABUSE & HARASSMENT IN THE QUEER FEMALE COMMUNITY
(artwork by Henn Kim)
**Trigger Warning: the following survey contains questions about verbal, physical and sexual abuse**
In the wake of the #MeToo movement, the Weinstein scandal and others - all of which focus mainly on male abuse of females - I have been asked to write an article about the ways in which abuse and harassment manifest themselves in the queer female community.
If you are a queer womxn, your stories are valuable to my research, and I believe this is a valuable topic to be discussing within our community.
