I suppose the street violence could actually be Jolyon's infamous defensive weapon recommended to women: the Tut and Move Away, and that's why he's in trouble with C.
However suggesting that there's an organised GC wing of women Tutting and Moving Away somewhere under Jolyon's command is a bit of a stretch, particularly considering the massed evidence that most women regarded the T&MA as.... well. A glaring incident of foot in mouth syndrome shall we say?
