The more formal name for it is the Royal Christmas Message, and it started with King George V in 1932. It is now broadcast on radio and television in Britain and across the Commonwealth. In the US, you can see it on C-SPAN because they usually broadcast it or if you live in a US state along the Canadian border since the Canadian Broadcasting Corporation (CBC) also televises it..
Trans advocate Munroe Bergdorf, frustrated by another speech in which the Queen failed to mention her British TBLGQ subjects, took to social media to give her own alternative one called 'A Qween's Speech'
She also made it clear she wasn't trying to deliberately pick a fight with the Queen.
“I’m not trying to cause beef with the Queen, but it’s very frustrating to see institutions of high influence glaze over the issues and sprinkle sugar on things when things aren’t going very well. Bergdorf said."
"To not even mention racism, sexually transmitted diseases, gender-based discrimination, or the rise in hate crimes since Brexit invalidates the experiences of so many people," she added.
“Let’s start with education, please think of the children. Take a moment to think about the young ones who still don’t see any representation or relatable role models in history, on television, or in classrooms."
She also talked about some of the progress being made, and laid out ways in which Britain can improve when it comes to TBLGQ rights issues.
Here's the video of Bergdorf's speech.
