My current t validates that what I experienced with ex-t was harmful. She is disgusted with my ex-t and has no problem expressing that disgust. She wants/wanted to know what I experienced so she better knows how to help me. She has also told me about a few unethical t's she's had to fire. I think a good t will acknowledge that not all t's are good, and not all are bad. So, hopefully you won't have to feel like you're slagging the profession off.
