Life, as is on the ground rarely is the same as life as it should be.People hold illusions or overglorifications of groups of people and when there idealized version of these people does not correspond with the on the ground reality they feel alienated, disillusioned and walk away.
This process is further compounded by the reality that life, as is does not every give one ever the perfect opporunity to act because life, as is is complex, complicated and real life problems always get in the way.
There are a million reasons why something cant be done and a million and one why its not a good time to act.
Many people love to come up with the perfect theory or plan and will sit around forever trying to figure out every single possible problem, then beat themselves over the head and convince themselves that solutions cant be found.
We view the world diffrently, and our question is not why cant it be done but rather how must it get done and in the process of fighting for our goal and aim, we learn and strengthen our theory based on our experiance of interacting with our social conditiond of life as is as oppossed to life as it should be or what this or that flavour of the month revolutionary says.
By doing this and engaging we not only solve the problems the problems we are facing and in the process strengthen our theory but demonstrate the reality that not only can our social reality be changed, but rather that it must be changed and that the present social conditions are unnacceptable!!!
