Because physical force is easier to use in an argument than facts.
Being in the majority doesn't necessarily mean you're in the right. It does sometimes, but not always.
Because it happens to be more people supporting something, so more in agreement so to speak (not that majority doesn't mean they know best anyway).
only in a democracy does that cliche ring true> The U.S. was set up to be and is a republic: Quite different actually. In some """societies"" the majority has a much larger pile of rocks and an overwhelming larger number of rock chuckers.
Because they trample minority and dictator.
They either know more or none at all
There is Strength in Numbers.
They can beat the Minority up.
Or make life miserable for the minority.
What else would you suggest? Insisting on unanimity is rarely practical and, generally speaking, any given minority is unlikely to know more than the majority. And if you want specific knowledge, you can just ask for the majority opinion amongst people who have it.
It's the best way we have of coming to an informed decision, but it can be slow. Which is why we go for something more like a dictatorship in times of emergency. But would you really want that all the time?
That's all true, but picking out the times when the minority is right and then trying to explain that to the majority is a hiding to nothing. It's not a perfect system, but it's the best we've got. :)
Equating "majority rules" to "informed decision" displays your ignorance. "Majority rules" is the watchword of those who can't win by strength of argument or facts.
