The fact that transgender men and nonbinary people exist (and in the case of the former can have legal recognition of that fact) is enough to warrant the use of inclusive language. It's not about beliefs or about ideologies, its about ensuring that people get the care they need and that requires going beyond primitive views of 'basic biology'.
Around the world transgender people face discrimination, prejudice, harassment, abuse, sexual violence and even attempts on our lives. The transphobic moral panic coming out of English speaking countries is only ramping tensions up and making things more unsafe for those in coutnries that were already not safe. Internationally, transgender people are in danger and I for one welcome this initiative to help people escape that wherever possible.
The line-up for the event is set to have "many more" guests will be revealed as events unfold. Starting 4:00pm EST April 29th and continuing on April 30th 2022 (Which is 8pm in GMT and 9pm in BST.) The fundraiser is ran through the Tiltify program used by creators such as JackSepticEye for his annual #Thankmas campaigns. Keffals has already reached $2,865.11 of her $10,000 goal at time of writing, before the stream has even started!
