That is what I try to do. There is some cognitive dissonance to work through there. Like, when the inner ones come forward I accept them as true. I accept their stories and experiences, because I feel and know that it is their truth. I know they are not lying.
So in those moments it's all good.
But.
That stuff did not happen to me. It is not possible for it to be a part of my story.
I accept both of these positions as personal truth.

I was skyping with my DID friend the other night about this very topic. Her front ANP feels the same way about it as me. At least that helps me to know that this cognitive dissonance about trauma memories is a real 'thing' in DID. Because I KNOW my friend's experience was real, even if she doesn't.
I see the whole picture of her and her alters. My ANP friend, like me, only fully sees hers.
