Cool, some dudes are nice enough.  They make the cut not being douchebags.  But they only talk about ideas or activism or work.  And when deciding if they are worthy partners with whom to make a life, I have doubts they know how to wash dishes, take out the trash or bring chicken soup for an ill loved one without being told to like a clueless child.  In short, they don't know how to handle adulthood, thinking of adulthood as simply a nuanced grasp of entertaining things or society-level things.  The interpersonal is nonexistent, even though that's the obviously basic starting point.
