I think one issue with thinking this way is that who is stronger and who is weaker isn't always so easy to suss out, particularly on the margins.

To give an example from my own life/experience, I'm an American and Canadian woman, but I'm also a disabled lesbian. I feel uncomfortable when I go places (e.g. Ikea) and see Muslim families where the men are dressed in Western clothing and the women are niqabis, because it's an outward signal to me that they follow an interpretation of religion that is sexist and homophobic and are likely to be hostile to my existing.

There can be power overlap between the weakest members of the stronger community and the strongest members of the weaker community.

For the record, I don't have those feelings around all people of Middle Eastern descent or people who are visibly Muslim but not displaying an adherence to a particularly conservative interpretation of their religion (e.g. a hijabi in Western clothes or a group where some of the women are hijabis/niqabis and others aren't). I do have those feelings around white people who similarly display such conservative religious leanings (Amish, Haridem, etc.). It's purely ideological, not ethnic or racial.

The thing is, as a native, I don't have a choice to be here, whereas immigrants do. So why am I assumed to be the 'stronger' one, and why should ethnicity and religion override any other power dynamic?
