The “principal contradiction” refers to the idea that there is some original or primary form of oppression that gives rise to all the others. ... Of course, there is really only one purpose for making such a claim: to persuade others to join you in your single-issue activist campaign, under the pretense that once your pet oppression is eliminated, all other forms of marginalization will subsequently fall by the wayside too. But the thing is, there is simply no evidence for a principal contradiction. ... There is no primary contradiction, just lots of different hierarchies that people may or may not endorse.

Accusations that IP is inherently “narcissistic” and “divisive” have become quite prevalent among EC-centric leftists lately. [...] In addition to disregarding all forms of non-EC marginalization, accusations that IP activism is inherently “narcissistic” or "divisive" severely confuse cause and effect. After all, I’m not the one who is “obsessed” with my identity. [...] It’s the people who harbor anti-trans attitudes who are obsessed with my identity, not the other way around! While I would absolutely love to live in a world where my trans identity was not especially notable or worth calling attention to, these people insist on making an issue out of it. Furthermore, by making a distinction between transgender people (who they single out for discrimination) and non-transgender people (whose identities and experiences they respect), it is they (not us) who are the ones being divisive. Once we acknowledge this causality, it becomes clear that IP is not an expression of navel-gazing or narcissism, but rather a form of organized resistance against those who are actively trying to delegitimize and disenfranchise us.

Here is how I describe the concept of privilege to skeptics: Do you believe that marginalized/minority groups face discrimination and are as a result? If the answer is yes, then another equally valid way of describing the same situation is to say that dominant/majority groups are relatively advantaged in comparison. “Privilege” simply refers to those advantages. One of the reasons why activists frame such matters in terms of privilege is to illustrate how *all of us* are impacted by unjust hierarchies and systems, even if it is not always apparent to us.
