While political reform is considered a heroic act, social reform is almost (always) defied.
The major difference between the two is: who is threatened.
In political reform, the public is struggling with a higher power. That is almost like stepping up the ladder and attempting to reach the sky. As the (heros) attempt an act of reform, they are not presenting a threat to the public. They are facing a direction that is foreign and safe: numerous people who exist on a level that the public is not emotionally involved with, but awes and fears nonetheless.
However, when the issue of social reform comes up everybody in the society is threatened. The multiple hierarchies of beliefs and ideologies grow doubtful, each fearing that they might be broken down and forced to abide under the lead of a bad rival..an enemy.
What hierarchies fear should not be taken lightly. It must be realized that in order to survive in a very (structuraly) diverse society, people spend most of their life striving to earn a category. Their life almost becomes a serie of working for and within a hierarchy.
From a young age, a person must swallow the hierarchy's food, what he/she likes as well as what he/she is disgusted with. The act of swallowing is the basic proof of loyalty and belonging. It is a person's ticket to love, growth, protection and safety. Basically, it is gaining a future guarantee. In such societies there are no hallways. There are only cubicals.
Actually, there are hallways! But people criss X crossing from a cubical to the other lose their status. They lose their earnt category. They become the crow that managed not the walk of the pigeon, and lost its own. A shameful history is attached to them forever after. The hierarchy they have left will always identify them as: the indecisive people, the easily manipulated and changed ones. As for the hierarchy that has received them, they are: the ones who were won over.
To sustain an identity in such a society, people must be born to a cubical and die in it.
Those who walk the hallways for a long time, refusing to choose a cubical over the other, are the threat. They are the hazardous social reform and are defied by all.
Fear of hall-wayers is a public (schizophrenia). It is a nonrealistic concern that exists in the collective mind alone, keeping cubicals on guard, causing some to lock up tight almost to the point of self-destruction.
Hall-wayers, on the other hand, cannot destroy. They might like to, but they cannot change already existing hierarchies. All they can do, is gather and accumilate untill a cubical of new ideas and social beliefs contains them.
Simply put, they are nature's attempt at sustainability.
