conforming to a minority

Minority group of people are more powerful in some extent as they occasionally change the continuing norms and become majority as well. For example, in Hindu society there was a norm to sacrifice life of wives after death of husbands during 18th century but the minority group was against that norms and protest for getting rid of that unscrupulous activities. After decade, they finally be the majority group and establish new way of 2nd marriage. That's the way of changing social norms by the minority group.
