Or is it?
For example, in a manner of speaking, I belong to the 'tribe' which promotes EVs over fuel-cell vehicles. I choose that position not because I want to 'belong' to a an arbitrary tribe, but because there are many distinct advantages with EVs, and relatively few advantages of fuel-cell cars. Do I gain pleasure by seeing the other side 'humiliated' or 'defeated'? Well, one of the greatest sources of humour is in imperfection. If those imperfections are true, then a certain amount of satisfaction at a technology's defeat (along with their adherents' misguided beliefs about that tech) is perhaps justified.
A similar argument could be made for direct selling (dealers versus Tesla). I wonder which side most of us would belong to, and if that's an arbitrary tribal instinct, or just common sense.
