Yes, I definitely think there must be some kind of generational bloodline component to it, maybe not for all idols, but definitely some.
For example I found it really sus when I found this pic of Huen+ng kai's (for those who dont know, he is a t+t member) dad, doing the 666 hand sign, that is very telling. Also that both of his children are now in the industry, they must have definitely been at the very least pushed into that direction by him.
Yesterday I watched parts of some variety show that kais sister who will debut soon was recently in, and behind her on the wall are also these ped+ swirls symbols that have been discussed here too.
Also when I look at some other idols baby pics, I occasionally found symbols or hand signs that have been discussed here and are sus to me as well. Because these symbols are kinda everywhere tho, it might not mean much, I will admit that.
For example this baby pic of mr with mickey mouse clothes (mickey mouse is a mind control symbol), but again, it could mean nothing too.
I also saw pics of a young niki (enh+pen member), as a young boy wearing a shirt with upside down crosses, unfortunately cant find the pic now.
Some children definitely surely are specifically "bred" for these purposes,...unfortunately.....
The fact that the childhood of so many idols is so unknown is already so weird and rings alarm bells.
Especially this generational stuff must go deep and I wish I would know more about what exactly all this means.
