It already is a free for all, across all areas of the boards. Mumsnet is now the transphobic parenting site.
From the government's report-it site:
"What is harassment?
Harassment is any unwelcome comments (written or spoken) or conduct which:
violates an individual's dignity; and/or
creates an intimidating, hostile, degrading, humiliating or offensive environment.
Harassment can take many forms including violence, threats, abuse, and damage to property. It can involve verbal abuse and name calling, offensive graffiti or post and can be received via text message, emails or social networking sites like Facebook or MySpace.
It may cause physical injury, mental stress, anxiety, or insecurity. It can also occur for a variety of reasons, including race, religious belief, sexual orientation, gender identity or disability.
Harassment is a criminal offence. If you are being harassed, report it. "
So, does calling a trans woman "he" violate an individual's dignity? Yup.
Would a trans person be intimidated on here? Yup.
Mumsnet allows harassment that is illegal.
