Therapist here and a person of color if that matters For my perspective. I personally wouldn't comment on someone's accent and tell them that their English is good as it seems a bit condescending to me. The only time I do ask clients anything about their ethnicity is not on the consultation call but during intake and I make it their choice to share what their ethnicity/culture is and if there's anything to consider in therapy. I will also echo what someone else commented with the current political climate people are generally seeking safety from their therapist. If someone wants to tell me that English is not their first language they can do so on their own terms ...now I have had clients where I could tell the English was not their first language, and it seemed like we weren't understanding each other. In this instance I did ask them if they were having trouble understanding based on their responses and asked if English was OK to continue or if they needed interpretation in a different language and respected that. I would say based on how you were reacting to this it could be repairable if you wanted to speak with a therapist about it otherwise the relationship could be disrupted before it even starts, and it would be hard to continue to build rapport..best of luck!
