It sounds like you're saying it's fine to be racist against whites, but offensive to do the same thing to your personal "in-group." Little ironic, lol.
Often, when people are referring to racism, they're referring specifically to Institutional racism. As a general rule (because everything is naturally full of gray areas) it's considered to be impossible for whites to experience institutional racism in countries where we're the majority. So while a PoC could certainly be bigoted against whites, it wouldn't be accurate to say that they're inflicting institutional raci…
Sorry, what? Considered by whom? Because we should have a word with these people about how unimaginative they are.
For one thing, there are plenty of ways a member of group X could experience institutional racism in an X-majority country. Perhaps they live in a Y-dominated region of the country, or work for a Y-owned company, or group Y has more political/economic/cultural power in society despite being a minority, or they work for an organization whose policy is to hire and promote Y preferentially.
More generally, I don't see the purpose of desperately insisting that institutional racism can never affect group X. To say that group X can be harmed certainly doesn't mean that group Y isn't harmed more. It's a weird and pointless linguistic game that harms the purpose of achieving equality of opportunity by gratuitously driving away allies.
