You are right, I should have said "big difference" instead of "deep line". I tried to focus on how meaning is conveyed while neglecting my own language. And there's a big difference between "big difference" and "deep line".

Back to the original topic, yours also serves as an example of how easily damage can be delivered through being systemic. I'm confident it's not hard to produce many cases that qualify as systemic traumatic abuse, but it's an exercise I'd rather not do today.
