TLDR: Those who are agnostic / spiritual or believe in "souls" are a lot more likely to accept gender ideology, because it is essentially the same thing.
I have a very dear friend who has been caught up in the hatred of "terfs" and believes the whole "trans women are the most vulnerable."
She is a very empathetic person, and very smart. However I have no doubt that she is more vulnerable to gender ideology due to her past history of abuse, and her own mental health struggles.
I also suspect that, because she is agnostic and believes in the idea of a soul, that the leap to gender ideology and the belief of "a feeling inside" and "gender", (aka both made up things), is not difficult for her to blindly accept.
On the other hand, my religious friend (church of England) was a lot easier to "peak", because what she is taught I'd that God made you as you, and you cannot change it.
Has anyone else had this experience or come to this conclusion? Would love a discussion to flesh this theory out.
