Do you accept Cultural Norms or strive for Cultural Expectations

In a time when there are so many battles to fight, we all pick and choose which ones we invest our time and energy into. Too often I see people accepting the cultural norms of the time and place as opposed to engaging to strive for the expectations to improve the culture.  Yes, it takes time and energy to swim up stream against the norms but do we continue to dilute our culture by not being willing to fight for what is right?
