I'm skeptical of most claims of trauma. As a fan of premodern history, I have come to understand that 99%+ of all humans ever born experienced what would today be called severe childhood trauma, not to mention later adult trauma. And they carried on okay. So either you have to think that everyone in the history of the world had been operating with severe trauma that was causing terrible problems, or that the modern trauma dose/response curve is learned. And I just feel like the former is less likely.
