The newer generation's absurd humour annoys the older ones.
Early 90s was too weird then
Late 90s was too weird then
It is not like absurdity as a source of humour is new.
Memes are often short form low production value crowd sourced absurdity.
Also, I think the perceived destructiveness of memes is just their short form. You cannot build any sort of context in such a short form joke, so it has to rely on "You think this, but what about that!"
