They automatically support whoever they deem “less white”.
Sounds simplistic but this is literally the depth of their rationale.
If Jews are being killed by a white Nazi they’ll side with the Jews, but if the conflict is between Jews and Palestinians then the Palestinians get priority because they’re a bit whiter. If Palestine tomorrow declared war on Ghana, they would instantly turn against the Palestinians.
This is why they’re in full support of immigration until the immigrants were white people from South Africa.
