The first thing to understand is that allyship is not an identity but a practice. A person with white privilege does not get to proclaim themselves an ally to BIPOC but rather seeks to practice allyship consistently. And a person with white privilege does not get to be the judge of whether what they are practicing actually is allyship, because what they might deem to be allyship could actually be white centering, tokenism, white saviorism, or optical allyship instead.
