In societies, minorities can come to dictate the rules to the majority.
This usually happens because of asymmetry or because when the majority is either too flexible, too accommodating, or too indifferent.
A case of asymmetry is between smokers and non-smokers.
A smoker can sit in a smoke-free area but a non-smoker cannot sit in a smoker area, so the non-smokers will prevail even if they are the minority.
However, this can become an issue when the minority prevails because it’s more aggressive or more intolerant.
