I offered up the well established fact that you cannot have either racism or sexism against a dominant group by the group that group is actively oppressing and you said, "You are doing it here in this very same sentence."

It speaks to a misguided sense of oppression and victimhood as well as a lack of understanding about the sociological realities and the nuances within them.

Plus, your own links speak to institutional and structural components like "Discriminatory housing practices, redlining neighborhoods, underfunded education, lack of access to healthcare, racial profiling, police brutality and mass incarceration" and the like.

You've made my point for me.
