Hi! I myself have been hostile (and have definitely felt anger!). Especially in the last few years, due to my own personal situation. But I wanted to change this. I have come to realize that I can be reactive. Which to me, means impulsive in my actions, and angry / hostile in my words and expressions. I can also tend to jump to conclusions. None of this helps me feel better, and also makes the situation worse. It happens because I am hurt by what someone did or said to me, and I want to protect myself. Said person might or might not know what they did. They might or might not be in a place to care or understand. I think it's natural and normal to feel anger, and even hostility. At first, I felt bad about it. Who wants to be the offended person over there? But I realized that I have control over how I respond. I can change it. It takes work, on my part. I have to be mindful of my thoughts and feelings. One good bit of advice I have gotten from my therapist, is to step back when upset (leave the room, get off the computer, etc). It takes practice. I don't know how to get rid of anger. If there was no anger in the world, I don't know if people would care to help with atrocities or social justice stuff. Take care!
