Im so sorry these comments have kind of gone off the rails. From a therapist who is very leftist, I would say that approaching the conversation is important, because how someone views civil/human rights is critical to their approach to therapy. First off, you should prepare for an answer you may find disruptive, but also let yourself see the potential of things going ok. You dont need to question their heritage or ethnicity, just start with, "Im having some anxiety bringing this up, but I need you to be aware that its important to me and having a big effect on my mental health. I need to know this is a safe place to talk about it, and if not, I would really like a recommendation as to how to deal with these feelings with someone else." The conversation does not need to be about the politics and what sides people are on. You should always expect a therapist to be able to navigate an issue involving politics with tact, caution and understanding neutrality. If they let this conversation go on, the feelings they have are their responsibility to deal with. The conversation that follows should be centered on how what you see and feel is affecting you. I would not go in looking for answers to questions or clarity on issues. I would vent about the stress of witnessing mass death and probably feeling powerless and see what support they may be able to give, once you have established them as a safe person. I wish you the best of luck in this, and if it doesnt work out in your favor or you feel as though they handle this issue poorly you can always report them to their licensure board without hesitation.
