According to my count we're now up to 156, which means we have submitted more comments/complaints in favour of *more* trans people in Doctor Who than the anti-trans people have submitted against trans people in Doctor Who. AMAZING!!
One potential plan is to wait for this BBC complaints page to update: https://www.bbc.co.uk/contact/complaint-service-reports Hopefully that won't be too long after 17th December.
However, since the transphobes complaining about Doctor Who has been the topic of several articles lately, I might submit a Freedom of Information Act request sooner than that, and include a request for the number of comments submitted in favour of trans characters too (since that doesn't show up on the complaints count).
Then I might send a press release to every news website that published the "144 transphobes" non-news and see what happens. :D
