I don't want to be an observer

it has been a while since I have written here English. Maybe because I have been concentrated in my friends from Brazil. But, I think I can manage a little bilingual here.
Last week something very unfortunate happened and I saw it happening. It was not something good to see from any perspective.

I want to ask you, for whoever is reading this, when you witness an injustice or an act of prejudice what do you usually do? Do you just observe? Do you interact with the victim or do you side with the oppressor? Have you ever been in this position?

I haven't until last week. It was something very subtle, as I imagine how has happened in most places. So subtle that I took some time to realize that was really happening, and I saw myself frozen with no act in me. It was at least frustrating because I never thought of myself as an observer.

I acted later, after happened. I made sure that my opinion was pretty much the opposite of theirs, and then I left the place. Not knowing if I will ever return.
I am not keeping any bad feeling against those people, but I certainly cannot be in the same place where people pretend to be something and so openly demonstrate that they are not. Maybe they have never pretended, I, for instance, could not see what was right under my nose.

How do you feel when you realized that you have been deceived? How do you respond to that?
I am still having trouble to place myself in a good spot in my thoughts about that.
I am not an observer, I don't want to be.
I hope neither you.
Let's try to be more active, express our minds and hearts.
Let's be truthful with ourselves.
