Social What?

Thought that I have been mulling over for a while now. Why do we think that social skills are so important? I was at Bible Printing one day and the son of the printer was in the building - he's shy and being homeschooled probably doesn't help. Having no kids his age around is also an important factor in the equation. One of the other people with us on the way home made some dumb comment about his (the kid) being homeschooled and having no social skills and it really rubbed me wrong. Just the arrogance of assuming that because the boy found it difficult to relate to other people somehow made him dumb. Then I started thinking - when you talk about men who have changed history you don't deal with a list of people who are easy to get along with: Paul was a fanatic, Jesus was rather revolutionary, Einstein was lost in his own world, Voltaire was arrogant, to name a very select few. There aren't many worldchangers that I could think of that had real people skills. So why do we emphasize and place such a high degree of importance on being able to socialize? Is this a Christian thing, a fundamentalist thing that we have to fellowship with each other and if you can't do that your failing. Is it a school thing whereby those who attended "normal" classes make a clique and exclude those who are different because they don't understand them? Is it Biblical that we emphasize these skills? Does the Bible command or teach us that it is necessary to socialize/get along with people? (Aside: not talking about loving people here - thats obviously commanded). So, tell me what you think: is this emphasis Biblical or not, is it brought about by culture (if so, is it popular culture or Christian culture), is it important to ask these questions? or any other answer to any question you might want to come up with.
