Certain people have a monopoly on Western entertainment. Of course they claim they don't, but look at all the big names who own and manage cinema, music labels, anything.
Even if you refuse to admit that more often than not they share a.... facet of their origin, you have to admit that they are politically all the same.
Also, almost everything is owned by the few big companies held by a few almost identical people.
This is how we get identical products that bash Christianity, white people, men, heterosexuals, not fucking disgusting troons. Commie shit, whoring, abortions, romanticising drug use and underage promiscuity, etc. Identical cookie cutter leftoid shit.

Then people discover a whole new source of entertainment that, while not flawless, still has a lot more variety. Anime and manga still cultivates an actual fanbase most of the time. The creators accept that maybe their stuff will appeal to 14-year-old girls. Or older men. Or fasion-conscious young women. Teen boys in their angsty phase.
And they are okay with that.
The creator of that deep fried madness Chainsaw Man did not expect your grandmother or your 10-year-old to enjoy his shit.

You can still have entertainment that is for you. Not telling you to change your worldview, your interests and try to rewire your brain.

And the people owning Western media can not accept that. They want you to be forced to watch the newest Marvel shit with the annoying smartass black little girl. The nonsense stories, the forced leftoid bullshit. They have to make sure you are captive.
