Anti-Racist campaign promotion by UCC social media promoter

UCC social media promoter is black while the vast majority of United Church of Christ members are white.  The church’s website includes a page dedicated to “Racial Justice” which defines racism as “racial prejudice plus power.” This definition (which is not the one found in the dictionary) of racism is popular with some progressives, and is the justification for claims that only white people can be racist, and that other races can’t.
