The concept of generations is just a social construct. These kinds of things are mostly just selection bias. If what’s seen as someone from an older generation criticizes something done by a younger generation, then “generational trauma” confirmed. If an older person agrees with a younger person, it’s ignored. If someone of the same age group criticizes, it’s also ignored.

It’s especially ridiculous when considering opinions on something as subjective and inconsequential as a meme.
