She's correct because there is indeed only one race - the human race.
She's incorrect because she takes race from a US POV, which in itself is colonialist since US culture now equates with international. US based academic and popular theory on centred on race, mostly based on segregation laws and then trying to make sense on race outside of the 'territory' and experience. Jews 'pass' for white in the US - unless they go to temple where they're held hostage at gun point or children are spat on in the streets of Brooklyn.
Race isn't based on colourism, a term we now only ascribe to countries that are predominantly non-white to use light to represent 'fair' and deeper skin-tone to mean less beautiful/worthy/intelligent etc. There is unfortunately racism between people of the same or similar skin-tone too. Just because Whoppie is a WOC doesn't mean she can't be racist.
Whoopie made up she was Jewish years ago after a charity cookery recipe was full of stereotypical and quite hideous 'jokes'. Her PR at the time said she couldn't be anti-Semitic because she was partly Jewish. That's acknowledged now as a lie. Had she converted to Judaism, there's no reason why she couldn't religiously be a practising Jew, but she didn't, she changed her name that sounded Jewish because she thought it would help her ambitions. Kinda funny when you consider how many Jewish actors and industry insiders changed their name to anglicised version to make them more acceptable.
Before WWII, German (and European) academics as well as many others wrote reams of texts on 'the Wandering Jew' about how these 'Orientals' were like the desert dunes of their homeland, their exoticism and strangeness, so unlike the European. They lived all over the globe including Africa, India and S. America, but were often singled-out as a different race from the main. Their nomadic existence in tolerant (or not) host countries was apparently incidental, it was apparently their race that made them 'X' or 'Y'.
In more recent years, Jews are often called European even when they're born in the Middle East (or anywhere else). This is a political POV, not a scientific one, and it's why being anti-Israel can be anti-Semitic (although not always). Making Jews White is a way of making them European and thereby, by implication colonisers, not a race that has been victimised since Roman times. This is why what Whoopie said is at best dangerous ignorance and, taking her past into account and in the current climate may not be just a view.
