Communism

Marginalization actually serves the exploiter class, it is part of the degradation of conditions and inability to have solidarity with one another.

The invention of blackness, as in the US' extreme race rules, can find much of its origins in Bacon's Rebellion, where a multiracial, multiethnic uprising against the exploiter class was nearly successful. In response that same class began passing laws to ensure that the on-paper exploitation was reserved for people with darker skin, thereby inventing blackness for them and a form of whiteness for basically everyone else that would have previously identified more as English or German or Dutch, etc.

While anti-blackness has never died in the US, the same marginalization tactics continue to be applied for a wide range of issues. For example, claiming that immigrants "steal jobs" rather than recognizing that the exploiter class is simply paying marginalized people (and everyone else!) less and wantsaso redirect frustration to other exploited people rather than the exploiters making and profiting from. the decisions.

This is a long way to say that marginalization is primarily a divide-and-conquer strategy handed down by the people picking our pockets. We should reject it fully.
