I think almost every Filipino I've ever spoken to is self depreciating in that way, they might be the nationality with the most.... idk if self loathing is the right term but it's the closest I can think of in the moment. With the younger generation it's like they just reject their own culture and instead want to be American or just Western in general instead.
Though I guess that might be just a sample bias to some degree because that sample size consists just of "Filipinos that engage in western discussion forums/communities" and there could just be a ton more Filipinos that aren't self depreciating in that way that just also don't engage in foreign communities. Kind of like if you frequent weeb discussion hubs you'll get a very different picture of what westerners think of Japan than more "normie" communities.
