I would say there is a case to argue it can be a delusion. I would say you don’t have the authority to determine to what extent someone enjoys or relates to this delusion.
I saw a conversation on another site and I didn’t reply the way I wanted because it would have been insensitive. But that point of view has greater context here. People were talking about the AIDS epidemic of the 1980s and 1990s. I don’t know anyone who died from AIDS, or really felt connected to any celebrities who had it. However (especially since you bring up anime in the OP), there is an anime that is generally disliked for a few reasons, some of them valid. Since I am introducing it in this context, I cannot say what the anime is, because the “AIDS angle” is a huge spoiler, and I really don’t do spoilers. But it introduces this character near the end of the second season, and this character is all kinds of awesome and inspirational. You find out that what they’re doing is due to their time being short… due to AIDS. Or, if we’re going off the book those episodes are based on (light novel, not manga), it’s actually AIDS and cancer because, like, eff this character in particular, I guess. I don’t think I have to tell you how this arc ends. I will say if it were its own thing, if it were adapted separately from that anime with all the baggage, it would stand as one of the great drama series out there, it would have a lot more fans and attention on it.
So now we circle back to the OP’s question. If happiness coming from anime (or the other media) is invalid, what about sadness from anime? What if it’s an anime character with purple hair who really makes you care about a real-life social issue that doesn’t affect anyone you know? Does that make it any less real?
It’s not up to me to decide for you. I personally believe those feelings are valid. How you feel, I suppose, depends on factors that matter to you. For example, you might personally know someone who died from AIDS, and you’re like “well screw that fictional character, because that disease claimed millions of lives and I’m more affected.” But I would argue the story brings awareness. I would not argue that such a person is wrong for feeling that way, though.
If you know what anime I’m talking about, I’d ask that you follow my lead on the spoiler thing and not mention it. But I’m no one’s boss here.
Wouldn’t “GPT it” be easier/more likely to say?
I generally don’t use these, but Copilot (in Windows) uses one of them (I’m not sure which) and I’ve thrown a few questions at it when I’m bored. Nothing that matters. We have Windows 11 machines at work. I find AI amusing but I don’t take it seriously, and I don’t use it at home or on my mobile. It’s really not for me.
I don’t like Grok but they have a good name. I mean I don’t “like” any of them, but I like that one less because of its… the stuff it’s said. Mostly because of who’s been training it. But “Grok it” sounds better than Chat/GPT it and sounds almost as good as “Google it.”
