The concept of sharing freely and without fear is called the disinhibition effect. There is little inhibition about vulnerability with a stranger on the train because he can’t hurt you, so you believe. Of course, the possibility of being vulnerable and lacking perceived risk is part of cyberspace’s bait to lure us into its net. In real-world relationships like our families or the local church, it’s more challenging to “unlike” somebody. When bad things happen and hurts accumulate, we have to deal with them biblically (or not).
