Fear of Samsara in Others
You are beginning to notice the natural behaviors that we all carry out. This is a great thing as most people don't even take a moment to understand their behavior or how/why it functions that way.
As you are noticing like this, all kinds of weird side effects may start arising, as you are really shaking the foundation of the way you perceive the world. Fear for others may arise, sadness for others may arise, meaninglessness of the world may arise, great purpose for the world may arise, all kinds of things may arise because of this new noticing on behavior of others &amp; workings of the world.
What you are experiencing is a normal phase of investigating the spectrum of behaviors. Keep investigating and don't give too much importance to the fear or other feelings that arise from it (otherwise you may feed &amp; strengthen those feelings).
As you keep investigating, you will begin to understand why people play out these behaviors and you will begin to understand why this fear arises in you as a response. As your understanding of these things deepens, it will help you through this phase and eventually it will pass. What you'll be left with is better understanding of peoples behaviors, which parts of them are conducive to their long term happiness, which ones aren't, which ones you should support in them or not and which ones you should &quot;play along with&quot;.
If you understand why we all &quot;play out&quot; these behaviors, then it no longer appears as &quot;playing out&quot; because you understand why you are doing it and it's purpose. For example:
&quot;If I don't greet this person I just met kindly and go through the normal interactions they might expect, they may get upset and that would unnecessarily increase their pain/suffering, so better that I help them avoid that pain.&quot;
With this kind of understanding in your interactions, the feelings of disingenuousness should fade away.
Keep up this process and you naturally will come to love the world and everything in it. Understanding is love.
Additionally, I recommend meditating on the four Divine Abodes and trying to encompass those attitudes when interacting with others, this may be of great help.
