Most of the knowledge any random person on the street will have is wrong. In that it is a systematic attempt to understand the world outside liberal terms I am less opposed to it than other similar ideas. Especially as there is no direct path from astrology to antivaxx. It is all personal preference stuff. It is one of the least offensive manifestations of modern magical thinking.
Ehh, the first scene of the first episode is questionable. It is 50/50 among reviews if it is done well. Clearly not perfect or the discourse wouldn't exist. SAO was contemporary had more violence of that nature. It was clearly ment to be fun in that show and people do not give it the same level of hate. There is a charitable reading of the work that sees the author ment to say sexual violence was bad. Which is far enough from mainstream anime opinion that I think people have trouble processing it.
