Before, identitarianism took the form of explicit
laws which condoned or even required unfair treatment based on identity: Segregation, redlining, employment discrimination, etc.
The "New Left" of the 1960s struck down basically all such remaining laws, which was a tremendous accomplishment for their prestige, and (given such problems were sometimes neglected by them) against the prestige of the more class-centric "Old Left" that the New Left had schismed from.
This resulted in the Old Left withering away during the 1960s, meanwhile the New Left, having accomplished every legitimate goal it had by the 1970s caused every authentic activist to leave it then. The result has been the total death of leftism since the 1970s, with the Old Left dead, and the New Left nothing but a hollow shell composed entirely of Quixotic delusionals and shysters, pretending to fight something that no longer exists using tactics that can no longer do any good.
Now, all remaining identitarian oppression is implicit
, because while oppression can no longer legally be explicitly
done on the basis of identity, oppression can (and must!) be done for the purposes of capitalism, which requires that certain individuals (porkies) be given remit to oppress people for arbitrary reasons without accountability. That means all identitarianism that remains legal is done exclusively via that capitalism-shaped hole.
identitarianism using tactics to attack explicit
identitarianism is futile. Only and exclusively anticapitalism can have any impact against implicit
