Not to mention the fact that heterosexual, cis-gendered, christian, male is about a quarter of the US population[1], so categorizing it broadly as "many" vs "few" is already over-simplifying.

Intersectionality was intended to add nuance to discussions of discrimination (e.g. a black woman's experience is not reduced to "sexism" plus "racism"), but it seems to have popularly had the opposite effect of reducing everybody to a demographic venn-diagram.

1: If you exclude "male" and "christian" from the criteria, you do end up with a majority. If you switch "christian" to "protestant" then you make the minority even more stark, but anti-Catholic sentiment among protestants has significantly declined over the past few decades, so I don't think that historical division of categories makes sense anymore.
