It's really not. Have you spent so much as 5 minute of reading to educate yourself on the topic?
Do you have sources that detail the different "tiers" of racism? Is that even a real thing based on anything besides subjective opinion?
Don't all forms of racism fall under the core definition:
"Discrimination or prejudice based on race."
Shouldn't the end-game be to simply eradicate all forms of it? Instead of splitting hairs and starting infighting among those with that same goal?
