On proper decentralized protocols, the subjective view of each node _is_ their reality. Your perspective seems (to me) to be clouded by being accustomed to centralized experiences; this is very common. I think maybe we're talking past eachother in a pretty extreme way and I'm not sure why.

Ah, perhaps you'll understand it this way: do the Bitcoin Cash users, existing in their own stupid fork, negatively impact your use of Bitcoin? Think about that for a little and you'll see my point.
