We are equipped with a faculty to fight or take flight. Few of us are chased by tigers but we have other enemies; we can use our innate sense of danger whenever we smell trouble. 

We can fight injustice by the simple expedient of telling him he is out of order and do it as soon as we can. If our protest works we may well have the basis to negotiate terms. 

If however our protest is futile we can move on since without resolution of the injustice that place is, to us, morbid.
 
Whether we fight or flight we need what Edward Said suggests in his Culture & Colonialism: nomadic and migratory energy.
 
If we 'do nothing' we sit on the fence to lose our sense of identity and what confidence we might have had and are fit for nothing. 

By avoiding the issue we are paralysed by qualified satisfaction of our fundamental needs, and life will pass us by. 
 
And if we expose ourselves to what is, in effect, a morbid environment (it may seem, and claim to be benign) (one in which we cannot work best) we pay the penalty in being unable to reason effectively. 
 
 
Yet the resourcefulnesss, the potential willing commitment of e.g. the blind are wasted through being not recognised, nor realised.
