For some of those listed, like Anya Taylor Joy, yes there are US citizens that will dispute whether or not the person is white based off of their country of origin.
To be clear, I'm not speaking of my personal opinion when I say this.
I'm mentioning this to bring to light that the notion of race is a social construct where the classification criteria is dependent on who is classifying the individual. In the US, it's a different criteria than just appearance. Yes, white passing exists here, however country of origin matters. You can think of it as the effect of being "outed" in terms of the negative social effects that follow.
Anyway, both points can exist at the same time. As I had previously stated, the umbrella term xenophobia best describes a lowered interest in Gabriel when his country of origin is mentioned, but US racial dynamics are still a factor.
Additionally, I'm not quite sure why you were so heated by this discussion but yes. Let's get back to the updates.
