The official line in the WH is that global warming is an agenda perpetuated by the liberal media. Never mind that everybody else says it's real and happening even as we speak and may pose the biggest threat to human existence. The Iranian president thinks the Holocaust is a Hollywood invention. Never mind that there is overwhelming evidence to the contrary. IMHO people who deny either are at the basic level operating on the same wavelength. They only see what they want to see and hope enough idiots fall in line behind them to give credence to their ideas. But to ignore the future is worse than denying the past. The past can't be changed. The future can be.
