Those who have never tried electronic communication may not be aware of what a "social skill" really is. One social skill that must be learned, is that other people have points of view that are not only different, but threatening, to your own. In turn, your opinions may be threatening to others. There is nothing wrong with this. Your beliefs need not be hidden behind a facade, as happens with face-to-face conversation. Not everybody in the world is a bosom buddy, but you can still have a meaningful conversation with them. The person who cannot do this lacks in social skills.
