Let me expand upon what I said, which is my humble opinion: Liberals and many people DO believe it, including influential people. But the people who are really influential, really make the decisions, really manipulate stuff, they use these temporary inane agendas to their will, but they do not really believe in it.
People like George Bush (both o them) for example, he was the president and we know that personally he did not care for those things at all. In the same way, I think, were are other influential people in the US.
Who's really behind those things is pushing for degeneration while utilizing the guillible people who actually fall for it, but in the future it will be changed, rest assured, when they want.
