If Inner Firefly's suggestion rings true for you and you think it's possible/likely that she meant to say something empathic and validating (something like "I am aware that racism is a huge part of your life") but could have done a better job with her wording, maybe discuss it with her, see how you feel and give it some more time. Ditto if you find her on the whole very supportive and aware except for this one clumsy statement.

But if this seems to characterize her entire understanding of racism (like it's in your head, it's not such a big deal, she doesn't get what people are complaining about, she thinks people of color are acting like victims etc) then I think you'd better get out of there ASAP and find a better T. Racism can be very psychologically damaging (in addition to all the other ways it's damaging) and you need a T who really gets that.
