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 antisemites 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.

This is what we see these days. Trump and his followers lying is normalized, i.e., they are not “obliged to use words responsibly”, whereas anybody argues against trumpists is.

They fear only to appear ridiculous or to prejudice by their embarrassment their hope of winning over some third person to their side.

This is what changed since then. They no longer fear being seen as ridiculous or stupid. They embrace it.
