THIS probably IS off topic, but I'm curious. I think I get what you mean there. And yet, what happened to you happened, whether you remember it or not, and you are where you are. You've already lived through it, what ever it was. What changes if you remember extra details? I'm not saying nothing changes, just wondering what it is and why you'd be "a mess".
I also said, specifically, that what JL went through was worse than anything that ever happened to me. I was speaking of "physically worse", mostly, and I meant it in the same sense that you used as a broken ankle is generally worse than a sprained one. (There's a level of soft tissue damage where a sprain can be pretty hard to recover from, as far as that goes.) I don't think it makes any sense to pretend that "everything is the same" because it's not.
There are at least three aspects to this. that I can see. First is the physical nature of the abuse. It's NOT a level playing field. There's a difference between smacking someone with an open hand and beating them with a baseball bat and there just IS.
There's also a psychological aspect to it that manifests in a lot of ways, but, as an example, it's different to be raped by someone you thought should protect you, or someone who's a random stranger, or someone who's clearly an enemy. Might not be any physical difference, but I can see, potentially anyway, a big psychological difference.
Lastly, I think there will be differences on the receiving end. That's complicated, but the kind of thing I'm thinking of is, if you have a severe phobia of rabbits, and someone locks you in a room full of bunnies, that would be horrible. Wouldn't bother me at all. On the other hand, I have a "thing" about critters like bats.... It doesn't even have to BE bats, I just have to think it is. (Actually, I'm kind of the same way with birds randomly flying around too.) So, lock me in a room full of flying birds? Not so good. Do it to someone who likes birds? Much different deal. This is complicated, and you can sure run into minimizing while thinking about this, but it's also true that different things are going to affect different people differently. There's an interplay between all of it.
@ghotiff , I think you're exactly right, it's a problem when this topic turns in to some kind of competition. Just not useful. At least not that I can see. And it can happen from several directions.
"What happened to me wasn't all that bad, I should just get over it."
"What happened to YOU wasn't that bad, you should just get over it."
"What happened to me was horrible and there's no way I can get past it."
"What happened to YOU was so horrible there's no way you can get past it." etc.
None of that gets us anywhere worth going. I totally agree, accurately labeling stuff is useful. Keeping score is a different thing completely. But accurately understanding things? That seems pretty useful to me.
