I mean over all, people are getting more and more Liberal as we speak. Once the older generation dies off, then the Liberal revolution will really have taken its toll on conservatism. Also I am talking more about Social conservatism, not a bunch of Libertarians.
What you mean is that society is always changing, but that doesn't mean what are currently viewed as 'liberal' ideas will win; they may lose, to be replaced by some other set of liberal ideas, which may also lose, to be replaced by another set which win. People remember victories for change, not victories for the status quo, even though the latter are far more common.
