Imprinting and transference are real things, and the more you see the caregiver as a fully fledged human being, the more appealing that trap is.
This is just begging the question, I think! Transference being real requires the idea that the caregiver is a blank slate onto which projection occurs.
Did you ever develop a crush on someone who had a big positive impact in your life? Sometimes it can be difficult to tell if those feelings are about the person or what they did for you.
If you don’t know the person all that well, it’s plain to see.
Did you ever develop a crush on someone you never really interact with, and who had no positive impact in your life? Perhaps someone who has had a less-than-positive impact?
You don't know the person that well.
There's ironically a good example of this in the blog post:
"For you, the day [I burned] your village was the most important day of your life. For me, it was Tuesday."
Therapists can have race, gender, and age in the same way that it can be Tuesday. They just can't have race in the sense of having their village burned.
(And FWIW, it's very difficult to have an effective blog devoid of emotional content. I tried once and got accused of being a Markov Chain.)
