You are literally saying: don’t trust this guys experience, my girlfriend is a doctor. I don’t think it’s as strong a point as you think it is.

While true to a point... there's also just lots of things that might work for a minority of people but are major risks for most. Someone who has actually studied the risks around exposure therapy is probably in a better position to discuss the risks of exposure therapy; and how to manage those risks. The person initially recommending it made no discussion of this whatsoever, and implied it was perfectly safe.

We all see people advising stupid things every day, because it's worked for them so far. There's the lichtenberg wood burning people who explain how to pull out a microwave transformer and use it to burn patterns into wood... and fail to acknowledge just how likely it is to kill you.
