Here's a relevant Sartre quote from 1944:
“Never believe that [they] are completely unaware of the absurdity of their replies. They know that their remarks are frivolous, open to challenge. But they are amusing themselves, for it is their adversary who is obliged to use words responsibly, since he believes in words. The [bigots] have the right to play. They even like to play with discourse for, by giving ridiculous reasons, they discredit the seriousness of their interlocutors. They delight in acting in bad faith, since they seek not to persuade by sound argument but to intimidate and disconcert. If you press them too closely, they will abruptly fall silent, loftily indicating by some phrase that the time for argument is past.”
It is indeed quite boring, because their methods haven't changed much at all in almost a hundred years.
The depressing thing, is that it still works and that because so many people don't understand history, we are likely doomed to repeat it.
