(not answering last question cause it is for me too) this is an issue not exclusive to the j-idol industry. this is an issue seen in the global entertainment industry as a whole. look at nickelodeon. aikatsu and pripara are /not/ promoting that though. literally the inherent concept of being a performer is not promoting that and is something kids have always admired. there is a thing called "nuance". stop asking strangers on the internet to be your moral compass and think for yourself for more than 5 seconds, especially when these are subjects that trigger a lot of people that you present to them with no warning
