To put it bluntly, I have had to put up with other people's stupidity again recently. (I will not go into details but I have also had to do this in a university setting: the very setting were one would expect intelligence and open-mindedness to prevail.) This has brought to mind two pertinent quotations. One from the Bible, the other from an atheist. It seems that nobody can stand stupidity.
Even a fool, when he holdeth his peace, is counted wise: and he that shutteth his lips is esteemed a man of understanding. (AV)
Proverbs 17: 28
A stupid man's report of what a clever man says can never be accurate because he unconsciously translates what he hears into something he understands.
Bertrand Russell (1872-1970)
