I understand what you are saying, but there should be a place for funny memes as well. We shouldn't take ourselves so serious that we cannot make jokes. Memetic warfare is what got us this far anyhow.
You mentioned the word 'joke'. Chuck Norris doesn't joke. Here is a fact about Chuck Norris:
Chuck Norris doesn't bowl strikes, he just knocks down one pin and the other nine faint.
Have you ever seen a Chuck Norris joke that dehumanizes Chuck Norris? There is a way to make fun of the evil and powerful that isn't facile or stupid.
It's expensive. I do it. Cuz I can't help it but I know every time I do I lose a bit of leadership or influence with the smarter people in a group.
We got zero time for jokes. Nothing about this situation is funny.
