Think about it. You listen to some music, your brain will fairly rapidly inform you wether you are a) enjoying it, this is GROO-VEEE, b) it's doing nothing for you, I mean you don't want to vomit or anything, but you wont care if you ever hear it again, or c) this noise is horrible, it makes me want to tear of my ears and swallow them lest I hear it again and subsequently go out find the men/women who perpetrated this aural crime and kill them, slowly and painfully. This same simple decision process happens a billion times a day to every one of us... It works with people, smells, tastes, sounds, sensations, situations, in fact everything that happens will form some kind of opinion in your mind that lets you know wether you want it to happen again. It happens subconsciously. You don't even have to think about it and it goes on all the time. So, how can you not pay attention to it? How can you override it, suppress it, ignore it or disregard it to the point where your own tastes cease to matter and those of the people around you inform your entire view of the world? You must be entirely stupid or weak in order for it to happen.
So, there are people I know who claim to be fans of The Kings of Leon, Metallica and Beyonce. Somewhat possible, yes but nearly everyone I know who likes the first two may well think the latter is a visual treat (I don't) but would rather die than listen to her, and of course the other way round does too. I have friends who claim to be socialist, yet think that Boris and Cameron are the best next step for the country. I have many friends who display this dichotomy of opinion and they all have one thing in common, the fact that they have very little will power and strongly opinionated friends (of which I am one) who it seems they must follow or die. It's quite hard to cope with these people. I would far rather have someone with a view of their own, wether I agree with it or not, than a namby pamby yes person. A lively disagreement is as much fun as a sharing of the same view with someone as passionate about the subject as you. What isn't fun is the humming agreement of the non opinioned.
Please people, tell me what you really think, not what you think I want to hear.
