What you're seeing is the contrast.

People whose reality is so different to yours (and the reality of most of people that you respect) that it appears clearly wrong & invalid.

Don't mistake that as being proof of an objective reality though.

I know it's unsettling, but the existence of an objective reality is an illusion. It is Maya.

Everyone's reality is unique & is constantly shifting & changing. Most people allow their reality to bend to what they believe others perceive.

Think about it. Everything we know to be true has been perceived by our senses & then translated into this thing we call reality. We both share a superficial reality. We can interact peacefully & civally without getting emotional or resorting to violence. Our realities align but they are never exactly the same. We both hear, see & think differently when exposed to the same stimulus. We can reach a shared understanding in order to exchange value. These other people hold such a divergent reality that it is near impossible to exchange value with them. I find it difficult to even be in the presence. Their reality is incompatible with my reality. I don't try to shift their reality though, I usually just avoid interacting with them.

You believe in the idea of an objective reality.

I believe that reality is a divine play of illusion. That none of this is real. It took me many years to accept this & I'm not judging you for believing different.

Neither one of us can decisively prove that the other is wrong. It is a purely a matter of belief, whether you believe it or not.
