In my white privilege?

(DRUNK TW: SARCASM THAT MAY SEEM LIKE A BAD IDEA WHEN SOBER)

WHY DO I HAVE TO UNDERSTAND WHY THINGS THAT I SAY TO MY AZERBAIJANI COWORKER MIGHT BE OFFENSIVE, LIKE BEING SURPRISED THAT SHE IDENTIFIES AS WHITE, DESPITE THE FACT THAT SHE ENJOYS NONE OF THE BENEFITS OF ANY WHITE PRIVILEGE?

WHY DO I HAVE TO CONSIDER THAT MY ASSUMPTIONS ABOUT HER RACIAL IDENTIFICATION MAY BE RUDE, OFFENSIVE, AND INCONSIDERATE?

WHY DO I HAVE TO LEARN FROM MY EXPERIENCES?

FYI: Coworker was not even kind of offended and loved that I even considered my questions/assumptions might be, so PREPARE ME A COOKIE.
