What one generation finds ridiculous, the next accepts, and the third shudders when it looks back on what it first did.
A good example of this would be allowing women to vote. I bet when that idea first came up, most people laughed. Then eventually women were able to vote. Now most of us look back at those times when women didn't have the right to vote and we view those past generations as being barbaric.
What "ridiculous" ideas of today will be accepted tomorrow? What aspects of our current society will our grandchildren look back at and find wrong and shameful? Will we be able to tell them that we were part of the ridiculed group that led the change, or will we have to tell them that we followed the crowd?
