With all due respect, communication of non-trivial ideas is incredibly hard. And if the recipient is not capable of paying sufficient attention or understanding the message in its entirety, it’s not their fault, it’s sender failing to captivate their attention (compared to everyone else out there) or conveying the idea in its entirety (that is, why it’s important to them as well). That is, don’t call people “dumb” just because they failed to heed the warnings. At the very least, that’s not helping in any meaningful way.
