Exactly what's happening today...
"Never believe the anti-Semites are completely unaware of the absurdity of their replies. They know that their remarks are frivolous, open to challenge. But they are amusing their selves, for it is their adversary who is obliged to use words responsibly, since he believes in words. The anti-Semites 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." ~ Jean Paul Sartre, 1945
Substitute -anti-Semite- with white nationalist and this directly applies today.
This is why 'reason and discourse' will not win over fascist bigots. They already know they're full of shit, they don't care. They delight in keeping the conversation on the level of the juvenile delinquent. This is how they "own the libtards", they frustrate them with bullshit.
This is why you don't debate racist neo-nazis, you resist them by any means necessary. The haters are outnumbered, the only way they can win is to keep their opposition talking and debating, and not acting.
