Whether the ideology is political, cultural or religious/spiritual it is not something based on reality or on the here and now but on what people believe things should be or how things should be or are. Often ideology is used as a protective filter that saves us from seeing the vagaries of reality and give us the false comfort of an ordered universe. Even when ideologies accept the reality of the chaotic and unpredictable it is often looked at as something to be remedied or as something evil and sometimes as something to surrender to. Rather than putting on the glasses and seeing the world just as it is, we would rather eat the trash can because why not? We eat the trash everyday but in our ideological frame of mind we see the trash as filet mignon because the ubiquitous "they" "the authorities" and "the experts" tell us that it is filet mignon and "they know better than us" because after all "it is written...".
Let us take the ideology "democracy", a vague term that no one seems to be able to define precisely, people mention concepts like "freedom" (freedom from what?) or rights (often limited because too much "freedom" is a bad thing apparently) and "liberty". The ideology "democracy" like all other ideologies is nothing more than a baby's pacifier, given to you to suck on in order to keep you quiet when you want mother's milk but lacking in the nourishments you need. It is a promise to make you feel alright or give you meaning but that is all on the surface. You dine at the Cafe Ideology and you will find yourself munching on a Nothing Burger with a side of Word Salad while you await your turn to try the new and improved Bull**** Buffet.
