Yeah he is a hapa, to my understanding. For Tayler Hills just look at her post in the AMXF content thread. You can see the guy's face.
I'm familiar w/ that other one, but that situation is objectively terrible optics because the Asian dude is getting cucked. Whatever a man wants to do behind closed doors is his business, but allowing cuckoldry to be publicly advertised is insane UNLESS your express goal is to make Asian guys look bad sexually. Assuming that's not his goal, he's just selfishly diminishing the standing of Asian men in the public eye just so he can touch white pussy.
I do count hapas unquestionably. Wider society in most cases sees hapa men as Asian. Not a value judgment, that's just how it is.
