You are re-defining the term. Racism IS prejudice or discrimination against a race based on the belief that their race is superior. It can exist from any race to any race. Acting on prejudice based on race is racism. In order for “your work” to be valid, you must use the term “systemic racism”. If you had used that term your article would be correct. If you would like, I can send you a link to Webster’s Dictionary so that you can see the definition of racism.
