Why do we share?
Most would say it’s because these emotional triggers are being pushed. To a certain degree, yes.
My opinion, because we love to get the approval of others and like to engage in discussions that not only appeal to our interests, but also are said “just like we would say it”.
Through that process of sharing, you actually filter people and the discussions that might happen, so that they’re to your own liking. (Assuming you’re not living in a basement, thinking the world is out to get you.).
