Yeah, it has a meaning, but what I mean is something that actually happens: people often make equivocal fallacies, such as the reductio ad Hitlerum of the reductio ad Stalinum to say "hey, this worker union is fascist because it makes me earn one less penny" even if that's what not fascism means. Also happens with racism, so your example only makes my point stronger. A lot of KKK are like "NoOOOooOo, but these black bastards are being racist to me because they don't want me to kill them!". Just the same. They're using an equivocal fallacy so they can pass their Troy Horse through.
