Conservatives tend to "aversion" as their coping mechanism (at its extreme, this might be labelled "hate") whereas liberals tend towards "connection" as their coping mechanism (at its extreme this might be labelled "greed"). Interestingly in buddhism "greed, hate and delusion" are considered to be the 3 poisons. i.e. clinging to either greed or hate leads to delusion.

Isn't the fact that "hate speech" is a "thing" whereas "greed speech" is not evidence of a liberal bias?
