I'm not sure if we're allowed to debate whether or not this was a trans gender hate crime? But on a very general note, I remember at school there was always bullying and the poor bullied child was usually an easy target (overweight, too clever, not very intelligent, or any other feature that made them stand out). I was at school in the 1980s and I cannot even imagine what would have happened if a child had started coming to school dressed as a different gender, the bullying would have been unimaginable - not for trans reasons per se but simply for being different. Maybe children now accept this but in my day it would have taken a lot of courage for Brianna to be trans gender - I used to dread going into school after having a new haircut!
So, I'm just curious, those with teenage children, or who work with them, is this something that is easily accepted amongst young people nowadays?
(for added context, my school was v religious so we weren't allowed to wear dresses more than 2 inches above the knee, and boys weren't allowed hair touching their collar, amongst many other rules, so my experience might not be what others experienced in the UK in the 1980s)
