Hadn't thought of it as 'therapy culture' before,

but the question is a good one.
I think Rodger's reported reliance on therapists from childhood through to adulthood deserves more analysis than it has so far received, because it potentially speaks to a dark side—a very dark side—of the modern therapy culture. There has been a mad dash to blame Rodger's actions on the misogynistic websites that he was known to visit, with some claiming these sites warped his mind and made him murderous. There has been far less focus on the therapy culture which by all accounts, and according to his family and friends, was a far more longstanding part of his life than his Internet habits.

In other news, I will shortly be going to rent a floor sander and buy the abrasives and a really good brush.  Hopefully I can make use of all of them without injury.
