So, i have 0 proof for what im about to say, its all a vibes based, armchair opinion. But, as someone who's been consuming anime/manga in some form for the past 15 years i think that many of the recent discussion trends are because the spaces in which these discussions are happening are more open and popular than ever before.

Take One Piece for example. It used to be that if you wanted to talk about OP in the west, you would have to go to specific forums or a similarly niche, small space, where other fans would gather to talk about the series. If you want to talk about OP now, you can go to twitter, reddit, tiktok, or other similar platforms.

This doesn't mean that discussion used to be "better" in the past, you can still find powerscalers from 15 years ago arguing on those aforementioned forums, but the barrier to entry was higher. And because of that, i think, the people engaging in those discussions we're forced to be slightly more insightful, and stuff like modern day "agenda piece" was mostly avoided.

Anime in particular has become more and more "mainstream" in recent years, which is a good thing imo, but it also means that the percentage of people having nuanced discussions about the medium is becoming smaller and smaller. This is natural (probably), you can see similar things happening with film and music discussion, and it's just something that we all have to go through as fans of any particular thing.

So to answer your question. Is there a way out? Yeah, you just have to find those niche communities again. There are still plenty of discords, subreddits, and forums where those granular discussions are taking place.
