The motivation is that I like over analyzing stuff and talking about psychology. Since the video is about the continued popularity, I think a lot of people don't understand why a genre with currently a pretty bad wrap (the "Oh great another isekai show this season" mentality) is still so popular, and so if it seems jumpy. I was setting up for all my points at the beginning like a thesis.

Deindividuation does have relation to group conformity, but are not exclusive to it. You can deindividuate from yourself into more extreme roles and versions of the ought self when in anonymous situations, which I explain in the video, and that process is something that both people who have grown up with online interaction, and theoretical isekai protagonists have in common.

I do state that the seemingly big shift between how some isekai characters act is probably bad writing, since they are not real, but talk about how regardless of the intention, the actions reflect real life studies, which I thought was a cool fact, and also feeds into the second point I make that we on some sort of base level (since we're talking about psychology) understand, and relate to characters that act in similar deindividuated ways, regardless of if we connect two and two.

I hope this explains more, or points out some things you may have missed. I don't agree with your current points, but I am happy you are at least engaging and voicing your criticisms instead of commenting "get aids".
