I am not the person you originally spoke to and I do not feel myself personally attacked. I am also not someone who has experienced this particular trauma but I have experienced some fairly nasty trauma in other fields none-the-less.
Your method of healing your personal trauma does not mend theirs and you are not presenting it in an empathetic way. You are trying to shame them and humiliate them for seeming silly for their experiences by trying to treat them as hysterical. There are ways to de-escalate a fear reaponse in people but that isn't what you're doing. You are not listening when someone routinely is telling you they aren't ready and trying to force your framework on them to make yourself feel justified. Recognize your audience. If someone is going to de-escalate their fear response it is going to be a conscious process over time, not from a random stranger on the internet swaggering up and saying "I have numbers". Who knows where the person you are talking to might be coming from? They may be in a community that is suffering a disproportional problem where that fear might actually be logical.
Rather than YOU feeling attacked about where she's coming and trying to strike back maybe realize - if you've managed to deal with your traumas you have the advantage of an emotional distance they do not. Use that distance to display empathy to that situation or back off because you are not going to make anything better otherwise. Do you want to be right or do you want to do good because sometimes you have to choose.
