Sociology is for marxist people everything but a Science: a Religion. Sociologists, whose Ancestors were the Moralists of the XVIIth Century make me think about TV or Networks: a Thermometer in the Ass of Society.
Sociology as TV or religion are useless if you are not against them, trying to destroy those fiendish mirrors, what is necessary to be free.
Whereas the father of this religion is Heidegger in nazism (in fact G.W.F Hegel is ten times smarter than Heidegger -the Teacher faith against the Soldier's one.), Jean-Paul Sartre is in French nation. This allows to understand the main difference between a true Science and a fake one as Sociology, ersatz of Science. There is no distrust of the Language in a fake Science.
