To add to my OP as it wasn't clear, I am all for LGB education in schools. Children should learn that some families have two mums, and that same sex relationships are absolutely normal and fine.
The issue is with the conflation of the T.
I do not support children being told that their body might be wrong if they like the wrong things, but that's ok because they can change sex.
I do not support children being told that some boys are actually girls and they should share toilets with them.
The problem is as the T has so parasitically latched onto the LGB it is pretty much impossible to protest this without being told you are homophobic.
