The Cliffs of Moher

[JoJo_Jost]

the real problem is:

Humans are so deeply convinced of their own convictions.

The silly part is that others are just as convinced of completely different convictions. 

And because everyone is so convinced of their convictions, the verdict is simple: the other person must be wrong.
People then promote themselves to being smarter or better informed, etc – and assume the others are too clueless to grasp their convictions.

The silly part, again, is that everyone else is running the same script.

In most arguments, at least one person (sometimes both) is simply wrong.
And if you’re part of it, that person might be you!

But of course, every argument presented here is unquestionably correct 


PS: In Germany, they say: "commas can kill:

“Let’s eat, Grandma.”
vs.
“Let’s eat Grandma.”
