Given that ego minimization comes from viewing oneself with respect to a broader group/context, what is the effect of isolating one’s identity from the group/context? Wouldn’t it have the opposite effect? If someone is constantly being told how different they are from people in a group, they are less likely to closely identify with the group. Or with any single group. The end effect is that everyone becomes isolated, purposeless, and egotistical. Obsessing over intersectionality achieves this purpose flawlessly. One can slice a loaf of bread only so many times before all that’s left are crumbs.
