[beffgkij] Skateboarding hoodla

Skateboarding is another activity whose skill is determined nearly entirely by individual practice and persistence.  There are many other activities and fields to which one could apply such generic persistence, but some people face social barriers into entry into those fields, so those people stick to skateboarding.  Therefore, we hypothesize that the set of people who have become good at skateboarding will largely consist of people who faced many social barriers elsewhere.  They will tend not to be very likeable people.  They will tend to get politically smacked down -- there will successful political efforts to ban skateboarding or move them to somewhere less visible, to the seedier parts of town.  All these seem to be true.
