I'm right there with you. IMO the best thing to do is tune this crap out. When you sense the anger shut it down. You know this has very limited value so don't waste cycles on it. I started the video made it about 15 seconds into it.
You also have to realize that people you admire and respect are not perfect. I share this experience. I've been let down by so many people. I learn they are fake or hypocrites. I learn they are gullible. Truth is, I probably disappoint them. We all have flaws and blind spots. I can truly say beyond Jesus (I'm a believer), I have no heroes. I have people I admire but I realize they are flawed people. All of us are. No one has arrived yet. I try to continue learning but never blindly trust anyone(not saying you do btw).
I'd say you care so much because you are just wired that way. I have the same issue. I wish I didn't care about many things so much. I'm able to let things go more than others but also less than still other people. Some people let things go to their detriment. Others can't let go of minor things. I have a friend that regularly tells me to stop caring about things so much. Its good to have that counter voice.
Don't fall into the trap.
