Why Approval of Same-Sex Marriages?

The recent change of public opinion regarding same-sex or gay marriages caps “one of the fastest civil rights shifts in US history” (Time). As late as “2010, a majority of Americans opposed them” (New York Times). “12 years ago, gay marriages did not exist anywhere in the world” (Der Spiegel). Why this rapid shift? After all, “only three per cent of America’s population is homosexual” (Canada Free Press). Why are Catholic Cardinal Timothy Dolan, Baptist Minister Mike Huckabee or Jewish Orthodox Rabbi Yoel Schoenfeld in the minority, when they state that marriage is biblically defined as an exclusive lifelong union between one man and one woman? Why does Rush Limbaugh feel that the gay marriage movement cannot be stopped, and why does Fox moderator Bill O’Reilly scorn at those who use arguments from the Bible to speak out against same-sex marriages? Is the destruction of “American Babylon” inevitable, and can only the arrival of the Messiah help us?
