You don't have kids. The stuff they get into can be ridiculous very easily. My experience has been paw patrol. There are a bunch of shows that have the same style, and you will see these shows a lot. Over and over and over. So much that any show that has even the slightest style as paw patrol becomes A paw patrol. The kid spiderman cartoon is a paw patrol for example.
You do learn the name of thier favorites. But you also see how much some things are the same. 8 bit Mario and Mega Man are different games, but they do look very similar to anyone working a full time job, coming home and cooking cleaning making sure everything related to your schoolwork is done, etc etc etc. Parents don't just hang around and be best friends with thier kids.
For me it would also be a matter of pride. If I dismissed all these things with the thought they're identical, but I cannot even name them, how can I in good faith claim to know them well enough to make such judgements? I would think myself arrogant and shallow. I'm far too prideful to think myself arrogant, and so I'm too prideful to dismiss something from a place of ignorance. Surely if the kid actually knows the names of the things and I don't, the kid's opinion must hold more weight than mine. I would only attack my loved one's interests from a place of certain understanding. I also can't understand having so little pride as to think as you describe.
You're thinking way too deep into it. It's not like that in real life. There is no attack, no ignorance. It has nothing to do with pride. It's just natural seeing things a million times and categorizing it the best you can. You don't understand how much kids watch the same exact stuff over and over and over and over and over and over. Its the same with video games.
If you could spend time with your kids 24/7 then sure, you'd be fine easily knowing and recognizing every single character they're interested in. That's just simply not realistic though.
Yeah I don't understand how a parent can not think deeply about their relationship with their kids. I don't think there should be such a thing as "thinking too deep" about anything to do with how to raise a kid.
Very likely they do think deeply about their relationship with their kids. Bringing it back to the comic: being hopeful their kid's interests translates to a successful and in demand career? Deep connections can be based on very simple, basic concepts.
