I've thought for a while that some offensive words & behaviour should potentially be punished harsher than others.
For example, vanilla insults like "F you" etc are somewhat indiscriminate verbal Diarrhea.
Whereas other use of language such as the N word or insults/comments towards Jews (ovens etc) strike me as a situation where the perpetrator is less likely to correct their behaviour with minor punishment measures. Stronger outcomes may actually help them potentially reconsider their life choices and lack of empathy. Perhaps consequences could escalate faster for these low IQ individuals?
