My goodness, are we having another bad fuckology day, or what? Any more naysayism and you'd turn yourself into another black hole, like many other silly Yids of your kind that suck and blow. BTW, at least their natural gas is somewhat dirt cheap and a whole lot cleaner than any of your coal, h2o and N2 fired alternatives, and it's not even radioactive for tens of thousands of years after the fact. Say again why you so hate humanity and don't give a flying puck about our environment. (isn't it that pesky Hitler cloning thing again?) - Brad Guth -
