If our culture is so far degenerated that unconstitutional civil rights laws for homosexuals, forcing states to change their definition of marriage (a definition that has existed in Western society for over 1,700 years), and abortion on demand are more important to people than discussing and understanding economics, then we have to change the culture of those individuals before we can talk to them about monetary and economic policy. Because it wouldn't matter if we endorsed a constitutional amendment to define marriage at the federal level as a union between any two individuals regardless of gender and forgot about the unconstitutionality of Roe v. Wade. Those kind of people would find some other social crusade that they would put before economics and freedom. It may be environmentalism, it may be "animal rights," or any number of things.
Social Progressivism is like a religion. It consumes their life and unless you can first convince the socially Progressive that history is linear and not vertical, you're wasting you're breath trying to teach them anything about economics.
