From some of the discourse I've seen, I've gotten the impression that some people think intersectionality is like math. Let me explain.
Some people think of certain identities as universally giving privilege (we'll say these have a value of +1) and some as universally taking privileged/causing discrimination/bigotry/etc. (we'll say these have a value of -1).
And what I've seen is that people will add these values and decide how hard someone has it based on the value of the product.
For example: A white (+1) Christian (+1) gay (-1) man (+1) would have a score of 2, since 1+1-1+1 is 2. (Keep in mind I'm not saying people literally do this sort of math, though I have actually seen charts that do, it's more of a way of illustrating a way of thinking I've seen.)
The problem with this, of course, is that this isn't how the world works at all. Depending on where he lived and his situation in general, that white Christian gay man could be bullied severely, called slurs, or even beaten and killed--all things you wouldn't expect going off a score of 2--because intersectionality is not like math. And because, in some places, this man's gayness would overshadow all his other identities.
Also, this mathy way of looking at things fails to consider how identities interact with each other. For instance, (and this is something several of my mutuals, but especially @dysphoria-things, have discussed in the past) a trans man's identity as a man does *not* serve to "cancel out" his being trans in the eyes of society. First, many won't even view him as a man. Second, even if he is viewed as a man by a certain group, he still may be subject to less explicit forms of transphobia. Not to mention the expectation many hold that he perform his man-ness in order for them to keep seeing him as a man. There's a lot more to unpack here specifically, but the previously mentioned mutual has already done many many posts on this, and is more qualified to speak on this than I am as a cis person, so I suggest you go check that blog out if you want to hear more on this topic.
Another example would be one of *my* identity intersections. That of being aromantic and allosexual. Now, being allosexual (not asexual) is not a minority identity. However, it by no means "cancels-out" my aromanticism. In fact, the specific combination of this majority identity (allosexuality) with my aromanticism actually leads to some seriously nasty assumptions and stereotypes. Because what do you think goes through the majority of people's (especially conservative's) heads when they hear "Oh I'm attracted to people sexually, but not romantically." Nothing flattering.
Point is, intersectionality is not like math. Having a majority identity does not necessarily mean that identity will always be rewarded (especially depending on the combination with a minority identity), and also this way of thinking is one thing that can start people down the "oppression-olympics/who has it worst" route, which is helpful and productive to exactly no one. The world is complicated, society is complicated, and people are complicated. And anything boiled down this much is usually inaccurate enough to be useless or actively harmful.
