Ah, yes. The reptile brain response to trauma: collapse AKA freeze. Many people may have the fight or flight trauma response, but many people with histories of trauma will freeze.
This is why saying, "I don't believe her bevause I would have fought him off." is unhelpful and dangerous. You're dismissing a common trauma response and condemning everyone who has that sort of response to not being believed.
Considering that people do not choose their trauma responses, critiquing how someone responds to danger feels like a special kind of victim - blaming. This is why I resist the idea that someone's behavior proves they weren't victimized; oftentimes a perfect full common and normal trauma response gets pathologized.
This in turn makes us less likely to believe survivors and signals to assailants what kind of person to target (yes there are ways to pick out potential victims who are likely to have a freeze response) or situations under which potential victims CAN'T fight back (lots of drinking/drugs).
We all end up less safe as a result.
