There is continued controversy around which bathroom trans people should use - that which is true to their identity, or that which matches their assigned gender at birth. While radical feminist women's groups characterise this as an issue of safety, it can also be seen as a fundamental contravention of trans people's rights to not allow them to use the bathroom that matches their identity.
Transgender people should use the bathroom that matches their identity
This is about basic human decency and dignity
Trans identities are valid
Being a trans woman is no different to being a cis woman, and they should not face different treatment.
Transgender people require treatment not accomodation
Transgender people suffer from an illness. Rather than trying to accommodate them, we should be trying to treat their mental illness. Transgender people need treatment, not accommodation.
