TQs tend to be obsessed with the found family trope. They long for that fantasy friend group of super cool, ride-or-dies that will become the "true" family full of acceptance and easily resolved disagreements.

I wonder if this is why the trope feels more and more shallow now? Gender-addled writers and animators don't want a real family, genetic or found. It's too messy, too challenging. They want the easy, minimal effort fantasy. 

 I think it was always shallow, exploring the trope merely revealed how shallow it was. A group of strangers could never be a replacement for a real family, love and acceptance as an adult won't undo a terrible childhood. But I agree with you that the "found family" was probably too close to a real family for their comfort, all they want to do is sink into their own little delusional world.
