Yes, this is because the experts don't feel threatened by noobs. They know they are actually experts, so they don't need to stoop to the level of picking on noobs to make them selves feel like experts. It's the "nervous middle classes" that feel a need to pick on noobs to reassure themselves.
PG wrote an article that describes this same phenomenon vis-a-vis nerds and popular kids in school:
If I remember correctly, the most popular kids don't persecute nerds; they don't need to stoop to such things. Most of the persecution comes from kids lower down, the nervous middle classes.
