"The goal of a definition is to introduce a mathematical object. The goal of a theorem is to state some of its properties, or interrelations between various objects. The goal of a proof is to make such a statement convincing by presenting a reasoning subdivided into small steps each of which is justified as an "elementary" convincing argument."

If you work through the existing structures you are going to be corrupted. By working through political system that poisons the atmosphere, even the progressive organizations, you can see it even nowadays in the US, where people on the "Left" are all caught in the electoral campaign and get into fierce arguments about should we support this third party candidate or that third party candidate. This is a sort of little piece of evidence that suggests that when you get into working through electoral politics you begin to corrupt your ideals.
