Broadly speaking, I define racism in three distinct subcategories: systemic, social, and cultural.

"Systemic Racism" would be forms of institutional racism that are government-supported and pervasive in the public sphere, i.e. police brutality, redlining, disparities in educational resources, etc.. These systems predominantly target/disadvantage BIPOC.

"Social Racism" would be how individuals actively and offensively mistreat one another based on racial differences per se. Many "antiracist" virtue-signalers would define this as merely "prejudice"...but "prejudice" implies an attitude or belief. Once someone takes that prejudicial belief and makes it actionable/behavioral toward someone else, their bigotry snowballs into discrimination. This can be perpetrated and experienced by people of all racial/ethnic backgrounds.

"Cultural Racism" would be the same principle as "Social Racism," except it involves peer pressure and groupthink...as GROUPS of people proceed to mistreat each other based on shared racial characteristics and the bigotry inflicted from those identities. Again, perpetrated/experienced by people of every race or ethnicity.

Organizations such as BlackLivesMatter are (rightfully) focusing on solutions to systemic problems caused by racism. "Systemic Racism" requires legislative action, in order to be confronted. But in order to solve "Social Racism" and/or "Cultural Racism," alternate solutions will need to be sought that probably cannot be accomplished through legislative action.

Of course, I'm White...so, in the eyes of many people (including other White people), I supposedly have no business commenting on any of this in the first place...
