My point is that with the current VR implementation the problem is not about rudeness, but fundamentally hampering personal communication.

If I go and meet with someone in person, I generally do it because I want to see them up close, face to face. If we are both wearing VR headsets that hide our faces, the whole premise goes out the window.

Eventually, VR headsets might overcome this problem by accurately portraying the other person's face in some way, but we are nowhere there yet.
