Not looking to be picky OP, but you spelt her surname wrong. It's Dzodan.
Dzodan wrote that essay as a woman of colour, and an immigrant. Intersectional feminism looks at the intersections of oppression black women and women of colour face both by being women, and because of being black/of colour. (Like Dzodan), structurally, politically and representationally. It was Patricia Hill Collins in the 1990's who then developed 3 main frameworks to analyse the various impacts of intersectional oppressions:
background (ideas, conflicts, history, debate);
social institutions
critical praxis
The theory however is not new - for example Anna Julia Cooper's 1892 essay "The Coloured Woman's Office" identified black and coloured women as being key to social change, because of the differing levels of oppression to which they are subject, and not just in terms of race and gender.
Other Latina women of colour have also developed theories as they relate to their experiences, because differing contexts means that how that oppression (gendered/racial/social etc) performs differently in different cultural contexts. Theorists such as Vrushali Patil and Marie-Claire Belleau look at how intersectionality can be utilised strategically, and how it impacts in terms of cultural hierarchies'.
It is important to recognise that Dzodan, Hill Collins, Crenshaw et al, were and are speaking in the context of being of colour/black, is also at the root of the theory of misogynoir by Moya Bailey (2010, I think, published by the Crunk Collective), and further developed by Trudy/Gradient Lair who also developed the theory of transmisogynoir.
Dzodan wrote that essay because she was frustrated, by any number of things, as a Latina immigrant woman because western feminism is sometimes a little ... cloth eared... to the specific situations that women Dzodan face and deal with, which too often western feminists co-opt or are tone deaf to.
