If we wait long enough, somebody of dubious credential will come along and say that pushing on the wingtips is just fine. Have at it.
No credentials, but a couple of questions:

1) what is the function of "drag pins"

2) how much load is put on things by pushing a glider around by the wing tips compared to opening the brakes at high speed, or by a Vne dive with brakes open? (and is either "necessary"?)
