You can break *any* aircraft by pulling too many Gs.

I think you might find that most of the modern gliders we fly are capable
of withstanding more "G" than the human body can take.
Overstressing a modern glider is unlikely to result in a catastrophic
failure unless there is already damage.
Remember the placarded limits have nothing to do with the design limits of
the glider. Most are placarded to +3.5 and -1 which was an arbitary figure
set by the LBA. Most gliders of the type we now fly exceed this level.
That is not to say that people should fly outside the placarded limits.
