I would say that I started out more neutral than a supporter. It wasn't something I thought about or heard much about. Like others have stated I assumed it was kind of like being gay. When my friends little sister socially transitioned at 13. I was mostly confused but respected name and pronoun changes because I didn't want to be seen as cruel. She had previous mental health issues and was bullied so I felt like she was delicate and I didn't want to say the wrong thing. Then she started hormones and the family was in talks about her getting a double mastectomy. She was so young I couldn't believe her family would support her making such a life altering decision. After she had her mastectomy (at 16) it was just so strange to me. Like this kid didn't know what she wanted to do for a career or if she wanted to go to school and they told her there was no rush to decide. Like what????? She doesn't have to rush making a decision on changeable life choices like school or work but by all means she can make a choice about something that has completely changed her life permanently. After that I got more skeptical of the movement and then on social media I started seeing the crap like "not being attracted to trans people is transphobic" or "misgendering is literally violence". I was done. I started watching Magdalen Berns' videos and started gaining radfem and GC views. From there I made it to the old GC reddit and haunted faithfully until it was taken down. I think being isolated in the pandemic and seeing JK Rowling tweet finally emboldened me to post.
