These people are really writing about themselves. Pure projection. They are the selfish ones. They can’t handle looking in the mirror of their own selfishness, so they project it onto you. They can’t handle within themselves their own vulnerability to disease, so they attack you. I believe that somehow they think they can ward off “evil” by blaming you for your own difficulties. It’s quite pathetic, actually. I wouldn’t take it to heart if I were you.
