From this comes the "gender is a social construct" and the idea that Truth is not Truth, but that your truth is different from my truth.
The inevitable result of these teachings, that reality is not objective and can be built to order so as to overcome its "oppression", can be seen in the current MacDonald's event.
According to the Gramscian theory, all the participants are victims, but it is their rebuilt "realities" that clash. The White is a victim of her mal-gendered form and sought to rectify that be rearranging her physical reality and corresponding behavior; the Blacks are victims of White oppression in the form of the other party seeking to impose her/his new reality on them, which was just the last straw.
