raising a point can be done tactfully and in so many ways... rather than an agitation...
this would imply that, in order to gain attention, the easiest way is to agitate or riot...
problems will come; the world is not perfect... and neither can all problems be fixed overnight...
and again, the intent of the opposition is not always to highlight the problem so that it may be rectified... rather it is to highlight the shortcomings which can then be utilised to its advantage...
