When a culture becomes established it will usually find a geographical home and forms itself into an isolated tribe. This geography can be a physical space or a position within a virtual space like an online platform.
Whilst that community remain isolated there is no issues with others. However if a different tribe gets too close then trouble exists. Different religions and political ideologies will fight if the same piece of land is inhabited by both of them.
In the on line community platforms do not like to intermingle. People all have their preferred way ov communicating . Should you dare to try phoning a text lover you will be ignored until you toe the line and text. Email addicts will not like to do FaceTime calls as their default comms are emailing .
We all need a place to belong from the family outwards and when we interface with the other then sparks will fly. While we stay in our bubble we get along with everyone as our identity through collective tribalism is not under threat.
