9/10 crackers do not ruminate in fear and dehumanization when they’re called that because there is no policy - historical or present - to oppress them as a group of people. Rarely do people say it with complete malice and desire for violence - it’s often said lightheartedly because everyone knows that the dynamics are just completely imbalanced. At worst they’ll be annoyed for 30 seconds and forget about it.
Hell, I’d argue honkey and redneck are more “offensive” because it’s a slur for poor white people, and this subgroup has and is still being targeted by the state today. But crackers don’t want to talk about class, even when it’s them who’s suffering.
