There could be many reasons why we, as a society, so judgmental towards each other. One possibility is that we feel as though we have a right to judge others based on our own little, specific world view. Alternatively, maybe we think that everyone else in the world is just like us, and our own relationship with other people is nothing more than a reflection of our own romantic or financial relationships. Maybe we think that. Who knows? But either way, it's a potential issue with judging others based on their social media, relationships, or other behaviors.
