Anyway social skills are pretty much just a filter between what you want to say (how many times to you think "this guy is an asshole" and don't say it) and what you actually say and part of this is the ability to pick up (and care about) what others feel and guess (and if really good) force their reactions and desires to match what you want them to do (see the end of the previous paragraph for an example).
None of that has anything to do with code. The compiler has no feelings and doesn't care about yours.
So if you want somebody in charge of the project, make sure they can deal with people (including assholes). If you want code written, accept that the people who can do it best have better things to care about than feelings.
