I'm sorry that you had to go through that

No need to add frustration to an already sensitive subject.
It sounds like ignorance to me. She probably doesn't put 2&2 together when bringing up these anecdotes.
Perhaps stopping her and telling her how upset you are would get her to understand what she is doing. When I feel like my T is blowing off something that means a lot to me, I go out of my way to tell her how much that topic is weighing on me.
I wish the best for you
