Why cryptocurrency communities are so tribal?

In my opinion, one of the biggest reasons that slow down adoption of cryptocurrencies is tribalism. One needs to understand that this is not a winner takes all and one blockchain is not gonna be able to serve the appetite of the whole world when adoption will come. Therefore, I think that we need to stop this mentality cause we don't protect our bags by being tribal, but by educating ourselves about other blockchains at the most fundamental level. For instance, Bitcoin can be viewed as a store of value, Ethereum is a smart contract platform, etc. Smart contract platforms come in different forms, architectures and designs. Each design has advantages and disadvantages. But ultimately, they will work and share values together without centralised bridges. And again this is not a winner takes all. But technologies with sound science behind them will survive the test of time.
