Whilst I understand the reasons, I don't see hysterical as a particularly gendered word anymore as I frequently use it in the context of humour- and I see it as applicable to both men and women in heightened emotional states.

However, I respect the ethos of the community and will avoid using it- but I think it a little unnecessary as more people using the correct terminology (because it wasn't a gendered word in the first place) can disassociate connotations.
