This whole thing is fucking stupid. (The OP, not your post.) They are obviously Asian men. Pretty boys, with some makeup but no worse than countless other popular singers. Prince, David Bowie, and Boy George, to name a few, were far more androgynous.
They are wearing male clothing. They have male haircuts. They look like young Asian adult males. The only thing is a bit of makeup, something that’s been part of popular music only for the last 50 years.
I asked some of my students, middle school and high school age kids, if they looked androgynous. They looked at me like I was crazy. They are males. Period.
Here are a few voice actors from Japan as examples of Asian performers. https://honeysanime.com/top-5-seiyuu-perfect-for-male-protagonists-japan-poll/
I wouldn’t discount casual racism as a factor. By causal racism, I mean that the OP may not think himself as racist and possibly doesn’t intentionally look down on Asians.
However, I first lived in Asia almost 40 years ago so I’ve talked to or read thoughts concerning Asians from thousands and thousands of Westerners over the years, and I see lot of racism. Mostly mild, like this. Sometimes worse.
It’s pretty easy to mock Asians. They’re shorter, usually with smaller physiques. They don’t even have much facial or chest hair. I’m not surprised at all to see them thought of as not human. That’s pretty much the history of the interaction between the West and the “Orient” from the very beginnings of direct contact. At least this time we didn’t get the squinty eyes thing.
Unfortunately, while there has been a lot of progress in getting rid of racism, or at least driving it underground, some people get super defensive about it.
Unconscious bias is something which plagues us all. Hell, I grew up as a very conservative Mormon with the traditional beliefs in the superiority of white males. It takes a lot of work to identify and eliminate bias.
As far as the taste in music. I’m not into k-pop, j-jop or whatever-else-pop. I’m not really into recent pop music from America either. I’m just another middle-age man approaching becoming an old man. I’d tell you to get off my lawn, but we don’t have lawns here.
