Deceived

It's not about belief, it's about truth.

If what you believe is a lie, do you really want it to continue?

I get the frustration when you bump into someone who refuses to listen, consider, and think, but anger, rudeness and murder?

Is your "truth" so important to you that those who can't "see" should be ostracized, or hurt, then it seems obvious... you are the one who is blind.

Anger isn't a sign you are righteously right, on the contrary, it is a sign that you deep down know it is true but so refuse to see it that you will protect the lie with evil action.

That is called deceived.
