The process of seeking truth is very isolating. People are very comfortable in their positions, they are comfortable in their beliefs and often it is impossible to sway them from these beliefs without generating considerable backlash because when you're exposing them to truth you're shaking away at the foundation pillars of their world. People naturally like to live in these pillars they've made for themselves in their perception of the world. Often, they will lash out at you unless they're receptive to what you're saying. If you invite them to open doorways into understanding, you can sometimes gain progress but presenting people with truths doesn't work for many because they simply protect those foundational pillars of their lives without question.
