As the Bible says “with much knowledge comes much grief”. It’s basically the opposite side of “ignorance is bliss.” The older you get, you know more. You don’t buy the bullshit and you see things for what they are. So yeah, thinks are fucked up and it makes you angry once you realize it. And I concur, some things you should be angry about. There is such a thing as righteous anger. God certainly has it, and as one of his image bearers, so do you. You’re supposed to. The thing that’s difficult is learning what to do with it and not let it poison you.
