Yes sorry, I did assume a western context, that’s my bad. I’ve only ever lived in Canada so I’m not too knowledgeable on progressive movements outside of the west. I would imagine though that the best course of action would be to state your alliance with those marginalized ethnicities in those cultures. For example, if you live in Kenya and want to see Somalians treated equally there then you should express your support for the Somalians, because not expressing that support will cause others to assume you hold the culturally “default” position, which in the case of widespread discrimination would likely mean they would assume you are anti-Somalian.

Basically all I mean is that if you want to show that you don’t care about race or ethnicity then show support for whatever group needs it the most in your community. By doing so you’re showing that you’re willing to accept those groups even though they aren’t identical to you. Sure that might seem like you absolutely do care about race, since you’re supporting those groups on basis of who they are, but a truly “neutral” position doesn’t exist in situations like this, as choosing not to say anything at all is showing that you’re okay with whatever the current dominant ideology is.
