I mean there isn’t, but also if you want to show other people are wrong (the racists) then you need to know what being wrong is and how to show that. This person doesn’t know and so would be detrimental in an actual debate as their points could be disproven and the racists would then believe themselves right. You have to make your arguments unasailable because the other side only want to prove you wrong, they don’t think they have to prove themselves right.
