As one example among many, a family I've lived with is what I'd describe as friendly, intelligent, and perfectly reasonable. They were also Buddhist. But they had some views I initially didn't understand. In one instance they found an individual with a crippling disability (leading to a sort of very awkward bow-legged walk) absolutely hilarious. In other they found people working in some really atrocious conditions at a fishery as comparably humorous. The issue is that they ultimately felt these individuals must have deserved such fates due to bad actions in a past life. After all, if they did good in their past life they would not have ended up in such positions in this life. So they viewed it as people getting what they deserved.
Never give people a divine righteousness, whether it be in religion or social belief held in a fashion otherwise indistinguishable from religion. They will find a way to screw it up no matter how unimaginably benevolent and harmless it sounds.
