While I disagree vehemently with Bill Maher on this (and virtually every) issue, I would note that he clearly has chosen not to lead the way in this effort. Until he is ready to set an example personally by sacrificing his own life, he should pipe down and stop expecting others to die in support of his foolish idea. All one needs to do is fly regularly and look out the window of the airplane to know that there are vast amounts of unused land and resources around the globe. He reminds me of Al Gore preaching at us about "global warming" while living in a house that has 20 times the carbon footprint of the average American home. The mantra of the left is "do as I say, not as I do."
